{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across a 960 by 500 pixel SVG canvas, updating its position in real time as the pointer moves. The visualization is built with React (using the `useState` hook) and renders the circle via an SVG `<circle>` element. Mouse movement is captured through the SVG's `onMouseMove` event handler, which updates the circle's `cx` and `cy` coordinates. The example uses D3.js v7 and ReactDOM to render directly into the page's root element, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c8f1cefb769406cafbb685980cf8563?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
