Generates charts via QuickChart.io using a shadcn-inspired grayscale palette, no dependencies required. You describe what you want in plain English or paste data inline, and it returns a clean PNG with proper styling. Supports bar, line, area, pie, and doughnut charts with sensible defaults for spacing, colors, and grid lines. The main thing that stands out is the opinionated design system using zinc palette colors and the emphasis on readable Y-axis labels, which the docs call out as critical after presumably having issues with unlabeled axes. Good for quick data visualization in chat without spinning up a plotting library, though you're locked into the grayscale aesthetic.
