{"version":"1.0","type":"rich","title":"Mouse follower","description":"This example shows a circle that follows the mouse cursor across an SVG canvas. It demonstrates React state management with the `useState` and `useCallback` hooks, where mouse coordinates from the `onMouseMove` event update the circle’s position. The visualization renders with React DOM into an SVG element using d3.v7, with the initial circle centered at the viewport midpoint.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af89547eee3f40af941f99d3ebb80aec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
