{"version":"1.0","type":"rich","title":"Smiley Face Follower","description":"A smiley face rendered with React and SVG components follows the mouse cursor across a 960×480 canvas. The face is composed of reusable subcomponents: `BackgroundCircle`, `Eyes`, and `Mouth`, with the mouth drawn using the D3 `arc` generator. Mouse movement updates React state via `onMouseMove`, repositioning the face through a `<g>` transform in `FaceContainer`. The example demonstrates combining React's declarative component structure with D3's geometric utilities for interactive SVG visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0d5235b1710042ce9a6ca5d53d7094fe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
