{"version":"1.0","type":"rich","title":"HTML Starter","description":"A yellow smiley face rendered with SVG sits at the center of the viewport. The example demonstrates a minimal React setup combining React 16.13 and D3 v5, using D3’s `arc` generator to draw the mouth path and plain SVG circles for the eyes and head outline. A vertical black line crosses the face, and all geometry is computed from fixed dimensions in JavaScript. This starter serves as a baseline for building interactive visualizations without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28a23167a0604c15938754c942da53a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
