# Area

Rendered from sample rows by viz_render in OODS Foundry 0.10.1, in each theme.

Generated from @oods/foundry 0.10.1

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.

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.
