# Chart playground

Make a chart with viz_render in OODS Foundry 0.10.1: a named pattern, or one of the 13 chart types with your own rows. Each chart comes back with its content hash, its narrative and data table, and artifact_certify's results.

Generated from @oods/foundry 0.10.1

Each chart you render here is a real call to `@oods/foundry@0.10.1`, running on this site's server. The page opens on a chart this site recorded, so nothing is called until you render. Each address can draw a few new charts a minute, with a cap on rows, and a chart already drawn comes back at once.

## Make a chart

A named pattern draws its own sample rows.

A chart this site recorded from OODS Foundry 0.10.1, so no call was made. Change anything, then render it here.

## The chart

### Its narrative

Usage Alerts sits in the high-impact/low-effort quadrant; Billing Revamp is large but expensive.

- Usage Alerts ideal quick win
- AI Assist promises biggest impact if we can fund it

## Certification

`artifact_certify` on the normalized spec viz_render returned, in light, brand A: coverage `certified`, conformant `true`.

- accessibility equivalence `a11yEquivalence`

  `pass`

- determinism `determinism`

  `pass`

- contrast `contrast`

  `pass`

- accuracy `accuracy`

  `pass`

**Contrast:** certify grades the series-to-paint assignment of the rendered chart (the compiled spec rendered through @oods/viz-render), against the requested CSS scope canvas. 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.

## The call

The viz_render call that drew this chart. Copy it with a short prompt for your own assistant: the same call to OODS Foundry 0.10.1 (`npx -y @oods/foundry@0.10.1`) gives the same contentHash.
