Generate an SVG, HTML, data-URL, or rasterized PNG chart from structured data. Supports 14 chart types (bar, column, line, scatter, bubble, pie, polar_area, radar, area, box, histogram, heatmap, gantt, combo) plus 'auto' which picks the best type automatically. Use this when you have data already in memory as a list or dict; for CSV input prefer chart_from_csv instead.

Return the full list of chart types supported by charted, each with its type identifier and a short description of what it is best suited for. Call this before create_chart or chart_from_csv when you are unsure which chart_type to choose.

Return all available theme presets and named color palettes that can be passed to the theme parameter of create_chart or chart_from_csv. Also returns a usage hint showing how to combine a palette with custom background and foreground colors.

Parse raw CSV text and generate a chart directly from it, without requiring the caller to pre-process the data. The tool auto-detects numeric columns for the y-axis and uses the first non-numeric column as x-axis labels. Use this when the user provides CSV content directly; for data already in a Python list or dict use create_chart instead.
