{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A red circle follows the mouse cursor across an SVG canvas, with its position updating in real time. Built with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates on a dedicated SVG `onMouseMove` event handler. ReactDOM renders the SVG, and the circle's `cx` and `cy` attributes update live as the pointer moves.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f2c67fde09df43d3b4863c9fbe0854d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
