{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow-outlined circle follows the mouse pointer across a blank grayscale SVG canvas. The React app tracks pointer movement via an SVG `onMouseMove` handler, updating React state with the cursor's client coordinates. This state drives the circle's `cx` and `cy` attributes, re-rendering the circle's position on every move. The example uses React `useState` and `useCallback` hooks within a functional component, rendered through `ReactDOM.render`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8fd316e4484c452f82ff7dbe56b76788?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
