{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A smiley face drawn as an SVG circle follows the mouse cursor across the viewport. Built with React and D3 v5, the component tracks pointer coordinates via React's `useState` and `useCallback` hooks within an `onMouseMove` event handler. The circle's `cx` and `cy` attributes update to match the mouse position, rendering at a fixed radius of 100 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a6753df403304416a85c18e9071c5c2a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
