{"version":"1.0","type":"rich","title":"Circle following Mouse","description":"A circle follows the cursor’s position across a 960x500 SVG canvas. Built with React and D3 v7, the example uses an `onMouseMove` event handler on the `<svg>` element to capture mouse coordinates and update React state. The circle’s `cx` and `cy` attributes are bound to this state, causing the circle to continuously reposition as the mouse moves. The SVG is rendered via React’s `ReactDOM.render`, with the circle radius fixed at 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/97d9131b7bbf47178d34fa80772f62cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
