{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A red circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves. Built with React and D3 v5, the app uses React’s `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle’s `cx` and `cy` attributes accordingly. No data source is involved; the visualization simply demonstrates interactive event handling and state-driven rendering with SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48ba0590fa2d4291ba068a31b9aa9055?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
