{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle follows the mouse cursor inside an SVG canvas. The example demonstrates React state management with a `useState` hook to track the cursor's `clientX` and `clientY` coordinates, updating on every `onMouseMove` event. The app renders a single `<circle>` element with a radius of 30, initially centered at a fixed midpoint, and uses React's `useCallback` to optimize the handler. Built with React 16.9 and D3 v5, the rendering relies entirely on SVG output without external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9326e3e5ab974917bc2bfd740c644423?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
