{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part III","description":"This example renders a single yellow circle that follows the mouse cursor across an SVG canvas. Built with React and D3 v5, it uses React’s `useState` and `useCallback` hooks to track pointer coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes in real time. The visualization demonstrates a minimal interactive pattern, combining React’s declarative state management with SVG’s native shape rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
