Gen Chart · gen-chart bundle Create polished, validated charts as a self-contained interactive HTML artifact or standalone SVG. In callers that display local Markdown images, also create an inline PNG preview. Interactive HTML includes dark/light themes, crosshair tooltips, legend toggling, and honest-by-construction axes. Accept pasted data (CSV/TSV/JSON/markdown tables), data files in the workspace, or plain-language descriptions with numbers. Use when the user asks to chart, graph, plot, or visualize data, metrics, or trends — line, bar, area, range, scatter, bubble, horizontal diverging bar, pie/donut, histogram, boxplot, or heatmap — or to beautify an existing chart.
