{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single dark circle tracks the mouse cursor across a blank SVG canvas. The example demonstrates how React state can drive D3 visualizations by updating the circle’s center coordinates on every mouse move. It uses React hooks, specifically `useState` and `useCallback`, to handle the `onMouseMove` event on the SVG element, while importing only the `arc` function from D3 v5, though the rendered output is purely a positioned circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad719906bdf24d8b97ee58f33a63f648?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
