{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part III","description":"A React and D3 interactive visualization displays a single circle that follows the mouse cursor across an SVG canvas. The code uses React's `useState` and `useCallback` hooks to track mouse coordinates, updating the circle's `cx` and `cy` attributes on every `mousemove` event. Rendered with React's `ReactDOM.render` into an SVG element, the example demonstrates how D3's SVG capabilities can be integrated with React state management for real-time user interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
