{"version":"1.0","type":"rich","title":"React Starter","description":"A React starter example demonstrates interactive mouse tracking on an SVG canvas. The code uses React's `useState` and `useCallback` hooks to manage and update mouse position state, rendering a single circle that follows the cursor within a 960×500 viewport. The circle’s center coordinates update reactively on every `mousemove` event, triggered through an SVG `onMouseMove` handler. Built with React 16.13.1 and ReactDOM, it renders directly to the DOM using the `ReactDOM.render` API, with the SVG output specified via JSX.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/463c783353bf4bb3b96a908e1b24d109?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
