| FRM-01 | Is each chart the right form for its question | Defect | −8 | Judge | 0 / 23 | Does any chart use a form that hides its main comparison — a pie or donut whose slices are too many or too similar to compare, a 3D chart, a trend shown as a table or pie, or a ranking shown as a line? |

| LAY-01 | Does the page hold together | Defect | −5 | Judge | 6 / 23 | Is there a large empty region the content does not need — a hole beside a tall chart, a half-empty row, a band of blank page? |
| LAY-02 | Does the page hold together | Defect | −5 | Judge | 1 / 23 | Are cards visibly misaligned — edges that nearly line up but miss, ragged bottoms within one row, uneven gaps between cards? |
| LAY-04 | Does the page hold together | Defect | −5 | Judge | 6 / 23 | Does detail outrank the summary — a raw table, a filter bar, or a minor chart placed above the page's main numbers or charts, or given far more space than them? |

| LAY-06 | Does the page hold together | Defect | −4 | Judge | 0 / 23 | Is color used in a way that encodes nothing or misleads — bars of a single series cycling through a palette, a rainbow color scale for a quantity, colored or sized marks with no legend saying what color or size means? |
| LAY-07 | Does the page hold together | Defect | −4 | Judge | 5 / 23 | Is there leftover scaffolding the author left in — placeholder or starter content, debug text, "lorem ipsum", stray test elements? |
| EXC-01 | What a reviewer who does this for a living would praise | Excellence | +10 | Judge | 1 / 23 | Does the page state its main finding in words — a title or sentence that says what happened ("Churn doubled in March"), not just what is shown ("Churn by month") — and do the charts bear it out? |
| EXC-03 | What a reviewer who does this for a living would praise | Excellence | +3 | Judge | 20 / 23 | Do the headline numbers carry a comparison — a change vs a prior period, a target, or a peer? |
| EXC-04 | What a reviewer who does this for a living would praise | Excellence | +6 | Judge | 0 / 23 | Is a key point marked on a chart where it happens — an annotated spike or dip, a target line, a highlighted series or bar with the rest muted? |
| EXC-06 | What a reviewer who does this for a living would praise | Excellence | +5 | Judge | 0 / 23 | Is most of the data drawn in a neutral gray, with one accent color reserved for the subject — the series, bar, or period the page is about? |
| EXC-07 | What a reviewer who does this for a living would praise | Excellence | +4 | Judge | 1 / 23 | Are a chart's series or pie slices labeled directly (at line ends, on the slices) instead of through a legend the reader has to look back at? |
| EXC-08 | What a reviewer who does this for a living would praise | Excellence | +5 | Judge | 23 / 23 | Does the page explain its numbers where they are shown — how a measure is defined, a filter or exclusion applied, a method note, or the sample size behind a rate? |

Is there a question in the brief that no element on the page answers?
Does the page answer what was asked
How to check: Go through the brief's questions one at a time and name the element that answers each. Quote any question with no element.
Requires the issue-health brief.

Not applicable: 1 · Unclear: 0
Is the page a crash or error screen, or a shell where most panels show no data (error messages, spinners, blank cards, "failed to load"), instead of a working dashboard?
Did every panel draw
How to check: A working page with one broken panel is WRK-02, not this. Quote the error or name the empty panels.
Raw YAML points: -25; gate results override the score formula.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Is any chart or table panel blank, an error message, a loading spinner, or a placeholder where data should be?
Did every panel draw
How to check: Name the panel and quote what it shows instead of data. A chart legitimately empty because a filter excludes everything, saying so, does not count.
Triggered in 1 of 23 captures: Mosaic
Not applicable: 0 · Unclear: 0
Does a bar or area chart whose bar length shows an amount have a value axis that starts above zero, so small differences look large?
Do the charts tell the truth about the data
How to check: Read the lowest tick on each bar and area chart's value axis. When the axis is hidden, compare bar lengths with their value labels — a bar labeled $1.5M beside one labeled $4.9M should be about a third as long; if it is far shorter, the axis does not start at zero. Floating bars that show a range on purpose (waterfalls, gantts, ranges) do not count.
Not applicable when: The page has no bar or area charts.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 1 · Unclear: 2
Does a chart or number promise a rate or share in its title or label ("rate", "share", "%") while its values are plainly counts or amounts?
Do the charts tell the truth about the data
How to check: Compare each title's wording with its values and axis ticks. "Win rate" with values 12 to 140 is a yes. Share labels on a pie or a funnel are not counts. A title naming a measure the chart does not plot at all is LBL-08, not this.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Does the same category appear in different colors in different charts?
Do the charts tell the truth about the data
How to check: Pick each category that is told apart by color in more than one chart (a region, plan, channel) and compare its color. Quote both colors. A single-series chart drawn in one default color does not count.
Not applicable when: No category appears in more than one chart.
Triggered in 1 of 23 captures: DuckDB WASM MetricFlow
Not applicable: 2 · Unclear: 1
Does a chart put two measures on two independent value axes with nothing telling the reader which series reads against which axis?
Do the charts tell the truth about the data
Not applicable when: No chart has two value axes.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 22 · Unclear: 0
Are side-by-side charts or small multiples of the same measure drawn on different scales with nothing saying so, so equal heights mean different amounts?
Do the charts tell the truth about the data
How to check: Compare the top ticks of peer charts that show the same measure.
Not applicable when: No two charts show the same measure side by side.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 8 · Unclear: 0
Does a line connect categories that have no order (products, regions, channels), implying a trend between them?
Do the charts tell the truth about the data
How to check: A line across time, funnel stages, or another ordered sequence is fine; so is a slopegraph or dumbbell between two points.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 1
Does any chart use a form that hides its main comparison — a pie or donut whose slices are too many or too similar to compare, a 3D chart, a trend shown as a table or pie, or a ranking shown as a line?
Is each chart the right form for its question
How to check: Name the chart, its form, and the comparison it seems to exist for.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 1
Do two or more charts on the page hide their main comparison through their form?
Is each chart the right form for its question

Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 1
In any chart with several series or categories, can some not be told apart — similar colors with no labels, or more series than distinct colors?
Is each chart the right form for its question
How to check: Name the series you cannot match to a label or legend entry.
Not applicable when: No chart has more than one series or colored category.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 1 · Unclear: 0
Are the categories of a ranked comparison in an arbitrary or alphabetical order when the point is which is largest?
Is each chart the right form for its question
How to check: A natural order (funnel stage, weekday, priority) is fine; so is value order. Name the chart and its order.
Not applicable when: No chart compares categories.
Triggered in 1 of 23 captures: Glyf
Not applicable: 0 · Unclear: 1
Is a single number drawn as a chart (a gauge, a one-bar chart) where the number alone would do?
Is each chart the right form for its question
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Do two charts show the same data in the same form, so one adds nothing?
Is each chart the right form for its question
How to check: A table beside a chart of the same numbers is fine, and so is a headline number repeated in a table's total row; those are different forms doing different jobs.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 1
Is a chart's point destroyed by its scale or ordering — one outlier flattening everything else, two measures of very different size sharing one axis so one is a flat line, or histogram or time bins sorted out of their natural order?
Is each chart the right form for its question
How to check: Name the chart and what cannot be read. A log scale labeled as one is fine, and so is one dominant value when that value is the chart's point.
Triggered in 20 of 23 captures: dbt charts, Quarto, Prefab, Chart.js, Observable, TanStack Charts, Prefab Reactive, Prefab Windows 2000, Semiotic, Graphene, Evidence.dev, mviz, ggsql + Vega-Lite, Marimo, Glyf, MDV, Observable live, DuckDB WASM MetricFlow, DuckDB WASM, Prefab MySpace
Not applicable: 0 · Unclear: 2
Does a time series start or end with a sudden drop or spike that comes from an incomplete period (a week or month still in progress, a partial first period), with nothing on the page saying the period is partial?
Is each chart the right form for its question
How to check: First look at the first and last point of every time series; if one breaks sharply from its neighbors, check the page's as-of date, window, and notes to see whether that period is incomplete and whether the page says so. A note anywhere on the page that names the partial period counts as saying so, and so does a partial point drawn differently (dotted, hollow, shaded).
Not applicable when: No time series.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 1 · Unclear: 1
Does any text overlap other text or cover the mark it labels (tick labels running together, data labels on top of each other, a title over a chart)?
Can everything be read
How to check: Quote the overlapping text and name the chart.
Triggered in 2 of 23 captures: Glyf, MDV
Not applicable: 0 · Unclear: 0
Do three or more charts on the page have overlapping text?
Can everything be read
Depends on: LEG-01
Triggered in 2 of 23 captures: Glyf, MDV
Not applicable: 1 · Unclear: 0
Is any title, label, or table column cut off, ended with an ellipsis that hides words, or pushed outside its card?
Can everything be read
How to check: Quote the cut-off text. Judge from within one tile; text that runs across the edge between two consecutive tiles is not cut off. Text inside an error message does not count.
Triggered in 9 of 23 captures: DAC, Chart.js, Observable, Prefab Reactive, Evidence.dev, mviz, Marimo, Prefab MySpace, Mosaic
Not applicable: 0 · Unclear: 0
Is any text too small or too faint to read at the page's normal size — tiny tick labels, pale gray titles or values?
Can everything be read
How to check: Use the full-resolution tiles, not the overview. Muted small supporting text that still reads is fine.
Triggered in 1 of 23 captures: Shaper
Not applicable: 0 · Unclear: 0
Are charts squeezed into cards too small for them, so their bars, lines, or cells cannot be told apart at the size drawn?
Can everything be read
How to check: Name the charts and what cannot be made out. Overlapping labels alone are LEG-01, not this.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 1 · Unclear: 1
Is there a number on the page whose unit (currency, percent, count, duration) cannot be found anywhere near it — not in the value, its axis, its title, subtitle, or column?
Can every number be understood without guessing
How to check: Name the number or axis and where you looked. A plain count whose title says what is counted ("Orders per week") needs no unit; a currency, rate, or duration does.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Does any title, axis title, legend, or column header show a raw field name, code, or placeholder ("sum_amount", "fct_orders.region", "Untitled", "Chart 1")?
Can every number be understood without guessing
How to check: Quote it. Category values shown as the data has them ("new", "solved") are fine.

Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Is there a percentage a reader could reasonably read against two different bases, with nothing saying which?
Can every number be understood without guessing
How to check: "Win rate" on a sales page is conventional. "35% resolved" could be of tickets created or of tickets closed.
Not applicable when: The page shows no rates or shares.
Triggered in 7 of 23 captures: Prefab, Prefab Reactive, Prefab Windows 2000, Graphene, mviz, MDV, Mosaic
Not applicable: 2 · Unclear: 0
Does a label contradict what is plotted — a unit that does not fit the measure ($ ticks on a count), an axis or title naming a measure the chart does not show, or a stated finding the chart itself contradicts?
Can every number be understood without guessing
How to check: Quote the label and the plotted values that contradict it. A rate promised but counts shown is HON-02, not this.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Do numbers or statements on the page contradict each other — a headline that disagrees with the table or chart it summarizes, parts that cannot add up to their total, two different as-of dates, or a note that points at content that is not there ("shown at right", "see tooltip" on a static page)?
Can every number be understood without guessing
How to check: Quote both sides of the contradiction. On a crash or empty page, intro text promising content that never drew is WRK-01, not this. An author's data-coverage date ("data through Aug 27") beside a tool's refresh timestamp ("data as of 09:25 UTC on 28 Sep") is not a contradiction; they state different things.
Triggered in 2 of 23 captures: Marimo, Mosaic
Not applicable: 0 · Unclear: 0
Is there a large empty region the content does not need — a hole beside a tall chart, a half-empty row, a band of blank page?
Does the page hold together
How to check: Count only space between and around cards on the page itself. Headroom inside a chart's plot area, an app's own sidebar or margins, and blank page below the last card do not count.
Triggered in 6 of 23 captures: TanStack Charts, Semiotic, Marimo, DuckDB WASM MetricFlow, DuckDB WASM, Shaper
Not applicable: 0 · Unclear: 0
Are cards visibly misaligned — edges that nearly line up but miss, ragged bottoms within one row, uneven gaps between cards?
Does the page hold together
How to check: Name the cards and which edge is off. Count only what a reader notices at a glance — a few pixels is not misaligned. Rows deliberately split differently (a 60/40 row above a 50/50 row) are fine.
Triggered in 1 of 23 captures: Shaper

Does detail outrank the summary — a raw table, a filter bar, or a minor chart placed above the page's main numbers or charts, or given far more space than them?

Is color used in a way that encodes nothing or misleads — bars of a single series cycling through a palette, a rainbow color scale for a quantity, colored or sized marks with no legend saying what color or size means?
Does the page hold together
How to check: Coloring each category the same way across charts is meaningful, not this; so is one accent on the subject. A category recolored between charts is HON-03, and tinted card backgrounds are LAY-05; neither is this.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Is there leftover scaffolding the author left in — placeholder or starter content, debug text, "lorem ipsum", stray test elements?
Does the page hold together
How to check: The app's or tool's own controls are never a defect — toolbars, menus, deploy or share buttons, breadcrumbs, framework footers, empty app sidebars. Raw field names as titles are LBL-02, and error output is WRK-01; neither is this.

Does the page state its main finding in words — a title or sentence that says what happened ("Churn doubled in March"), not just what is shown ("Churn by month") — and do the charts bear it out?
What a reviewer who does this for a living would praise
How to check: Quote the sentence and the chart value that supports it. A title that only names the measure does not count. If the chart contradicts the claim, answer no (LBL-08 covers the contradiction).
Triggered in 1 of 23 captures: Quarto
Not applicable: 0 · Unclear: 0
Do the headline numbers carry a comparison — a change vs a prior period, a target, or a peer?
What a reviewer who does this for a living would praise
How to check: Quote one headline number with its comparison.
Not applicable when: The page has no headline numbers.

Is a key point marked on a chart where it happens — an annotated spike or dip, a target line, a highlighted series or bar with the rest muted?

Is most of the data drawn in a neutral gray, with one accent color reserved for the subject — the series, bar, or period the page is about?
What a reviewer who does this for a living would praise
How to check: Name the accent and what it marks. A categorical palette used consistently is not this; it is a palette, not an accent.
Triggered in 0 of 23 captures: None in this capture
Not applicable: 0 · Unclear: 0
Are a chart's series or pie slices labeled directly (at line ends, on the slices) instead of through a legend the reader has to look back at?
What a reviewer who does this for a living would praise
How to check: Category names on a bar chart's axis are not this; it is about charts that would otherwise need a color legend.
Not applicable when: No chart has more than one series.
Triggered in 1 of 23 captures: dbt charts
Not applicable: 1 · Unclear: 1
Does the page explain its numbers where they are shown — how a measure is defined, a filter or exclusion applied, a method note, or the sample size behind a rate?
