Show HN: Claude Code Skill for generating any chart with natural language

I built a Claude Code Skill that generates flowcharts, architecture diagrams, data visualizations, mind maps, and math plots from natural language. Supports Mermaid, DrawIO, ECharts, GeoGebra, and Markmap. Just describe what you want and get interactive HTML or PNG/SVG output.
