Charts / Bubble map

Bubble map

Rendered by viz_render in OODS Foundry 0.10.1, in each theme, from sample data this site supplies.

Generated from @oods/foundry 0.10.1

No named pattern draws this type, so this site supplies the data: Stores in four made-up towns, over the same made-up regions.

Each chart is drawn live in your browser from the spec viz_render returned with it, so you can point at its marks. The SVG viz_render returned is the record: its hash is under each chart, and it shows where a live drawing would differ from it.

Findings

OODS-A11Y-R-14 (warn) Set portability.tableColumnOrder when rendering tables with more than two columns.

Contrast: Geo carrier paints were read from the rendered ECharts SVG, but geo color remains exempt from categorical contrast grading under the standing gradient-essential ruling. certify reads actual carrier paints from the normalized SVG rendered from the retained projected ECharts option. Geo categorical contrast remains exempt, so no canvas ratio is graded. Scope: light/A.

Certification covers charts only: it measures the chart's specification. A pass means no offered rule found a problem, not a general promise. An ECharts type certifies only when its data is supplied.
