{"version":"1.0","type":"rich","title":"Mouse Follower","description":"An interactive SVG visualization renders a single circle that follows the mouse cursor across a 960-by-500 canvas. The React component tracks pointer movement via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Initially positioned at the canvas center, the circle moves smoothly with the cursor. The example demonstrates state-driven rendering in React 17 with D3 v7, using plain SVG elements rather than data joins or scales. No external data source is involved; the visualization purely reacts to user input.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab53db1aeb7a485bb2b0de8df1b8f634?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
