{"version":"1.0","type":"rich","title":"Fork of Smiley face part 1","description":"A yellow circle follows the mouse cursor across an SVG canvas. The interface demonstrates basic pointer tracking using React state management, where `useState` stores the cursor’s `clientX` and `clientY` coordinates on each `mousemove` event. The `circle` element’s `cx` and `cy` attributes update dynamically from this state, while `circleRadius` remains fixed at 30 pixels. Rendered entirely with SVG within a React component, the example shows how declarative data binding enables smooth, responsive interactions without additional D3 utilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2d56e99801e4ddda616f6610240cc91?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
