{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The visualization uses React state to track mouse coordinates via the `onMouseMove` event handler and renders a single `<circle>` element with D3 v7’s selection-free React integration. The SVG viewport is fixed at 960 by 500 pixels, and the circle’s center tracks the clientX and clientY values directly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba5bcf1267454b84b081f46cf7a4f074?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
