# Chart Playground

Open /chart-playground/?example=<catalog-id> to edit an actual example from /examples/showcase/catalog.json.

Choose any catalog example and, when available, a chart within its original sample page. Edit its data, series names, title, legend, light/dark mode, one of the five presets, or an advanced JSON options patch. The full-width table supports numeric cells, side-by-side series, CSV/TSV paste and lossless original-data JSON. Quint shows every layer, its unit and its series upfront, including error-rate/typical-day arrays and availability/p95 row details. Supported colour, font-family, title and label controls map to actual runtime options. Quint internal label sizes and status colours remain fixed in the current renderer. Apply changes explicitly or reset to the original state.

Edits run locally in the browser against the original chart instance. JavaScript callbacks are not serialized or evaluated. Unsupported examples display their actual limitation. Premium examples remain part of the commercial offer; this editor does not grant production rights.
