Skill instructions
flint-chart: authoring and using a chart spec What you produce (and what you do NOT) Your output is the spec: the chartspec and semantictypes of a ChartAssemblyInput. You reference data columns by name. The host passes the resulting input to assembleVegaLite, assembleECharts, or assembleChartjs to get a backend spec. You write the input spec, not the output spec. And critically: - DO emit chartspec (chart type, channel→field mapping, properties) and semantictypes (field → semantic type). - Reference columns by name. How data itself gets bound depends on the situation — a URL, a host-side variable, or embedded rows (see "How data gets bound"). Embedding is fine for small tables; just don't re-serialize a large dataset by hand, since that risks truncation and silent value corruption and wastes tokens. - Transform data before Flint. If the requested chart needs aggregation, filtering, joins, pivots, derived columns, or long/wide reshaping beyond Flint's built-in static-series fold, use a
