{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the pointer’s movement. The visualization uses React’s `useState` and `useCallback` hooks to track cursor coordinates (`clientX`, `clientY`) and re-render the circle’s `cx` and `cy` attributes on every mouse move. The SVG element handles the `onMouseMove` event, while the circle’s radius is fixed at 30 pixels. The code imports React, ReactDOM, and D3 v5, though no D3-specific functions are invoked beyond the library’s inclusion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e77255e231b647128ec867a29be97117?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
