{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This interactive visualization renders a single circle that follows the mouse cursor across a 500x500 SVG canvas. The circle's position updates in real time through React's `useState` hook, which tracks mouse coordinates via an `onMouseMove` event handler. The code imports the `arc` function from d3.v7, though it is not used in the current implementation, and renders the SVG using ReactDOM. The example demonstrates a minimal React and d3 integration, with the circle radius fixed at 10 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
