{"version":"1.0","type":"rich","title":"React mouse follower","description":"A React mouse follower demonstrates a circle tracking the cursor across an SVG canvas. Using React's `useState` and `useCallback` hooks, the component updates the circle's `cx` and `cy` coordinates on every `onMouseOver` event, binding `clientX` and `clientY` to the SVG circle. The fixed 960×500 viewport starts the circle centered, and the lightweight interaction shows declarative state-driven rendering with React 17 and D3 v6 in the SVG namespace.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a30b0f887644890ba8f0a3774ba686d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
