{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across a full-screen SVG canvas. The visualization tracks pointer movement through React state, updating the circle's `cx` and `cy` attributes on every `onMouseMove` event. Built with React and ReactDOM, it renders a single `<circle>` element with a radius of 30 pixels, initially positioned at the center of the viewport. The example demonstrates a simple, responsive interaction loop where user input directly drives SVG geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0514409dd9f42c493084c0a1bd9418e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
