{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single gray circle follows the mouse cursor across an SVG canvas. The circle’s position updates in real time based on the mouse’s client coordinates, mapped directly to SVG `cx` and `cy` attributes. Built with React hooks (`useState`, `useCallback`) and rendered via `ReactDOM`, the app listens to the SVG’s `onMouseMove` event, updating the circle’s location on every movement. No data source is used; the visualization simply demonstrates interactive pointer tracking with React and SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0b831bfb2d564782aa097feb4966ccb2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
