{"version":"1.0","type":"rich","title":"Smiley Face Part 3 - Interaction with React","description":"A black circle follows the mouse pointer across an SVG canvas in a React application. The example demonstrates interactive state management by tracking the cursor's coordinates through React's `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` attributes on every `mousemove` event. It uses React 17 with the `ReactDOM.render` API, while D3.js v6 is loaded but not directly utilized in the visible logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
