Profile verification

• Marks bar/line/area/point/pie/donut bind explicit selected records. Numeric values must be finite numbers; numeric strings are not coerced.
• x is category/number/date; point requires numeric x, bar/pie/donut category. Line/area may use category, number or UTC date.
• Zero-baseline and arc share rules remain mark-specific; unit declarations must agree with supplied record units.
• aggregate none/sum/count/min/max/mean is available only on supported bar/arc/top-k paths, with contributor IDs preserved; count has no physical unit.
• Explicit empty records is legal for bar/line/area/point; filtering a nonempty selection to nothing is an error. Missing error/skip is explicit.
• Specialization mark arc uses channels: x y target. Positive finite weighted links with distinct nonempty endpoints; at most 200 nodes/1000 links. Nodes order by total weight descending; arc thickness encodes link weight, axis positions do not encode distance.

Profile defaults

Explicit file settings override eligible CSS, then these profile defaults and the common standard apply. Unspecified semantic facts remain unspecified.
