Tip: Claude Code's New /dataviz Skill Enforces Chart and Palette Discipline
Claude Code Docs·medium signal
Claude Code added a `/dataviz` skill that provides chart and dashboard design guidance plus a runnable color-palette validator, so agents produce accessible, system-consistent visualizations in light and dark instead of ad-hoc colors. Invoke it before writing any chart code (matplotlib, Recharts, d3, or inline SVG) to catch contrast and categorical-color issues that models otherwise get wrong.
