{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A smiley face follows the mouse cursor across a full-screen SVG canvas. Clicking anywhere increases the circle's radius by one pixel. The example uses React's `useState` and `useCallback` hooks to manage the cursor position and radius state, with event handlers on the SVG element updating the component. It renders a single SVG circle, updating its `cx`, `cy`, and `r` attributes in response to mouse events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6d4c6da9fc6e42ce8af3e43ef4262fe4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
