Rank microcharts chart types against a plain-language question about data ("is it trending?", "error budget", "part to whole"). Returns candidates with the reason each matched. Start here when you know the question, not the chart.

Full wiring detail for one chart by slug: import paths, its props plus the shared props, data shape, best/avoid guidance, a copy-runnable example, and sample — the example as JSON props you can pass straight to render_microchart.

Render a chart to a finished, self-contained SVG (styles embedded) plus its generated alt text — for surfaces that can't run React. Pass the series as data; put other props (value, target, curve, color, width) in props. Each chart takes its own data shape — get_microchart returns a valid sample to adapt.
