{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single dark circle follows the mouse cursor across an SVG canvas in a React-based visualization. The circle’s position updates live via React’s `useState` hook, driven by the SVG `onMouseMove` event, which captures the cursor’s client coordinates. Rendering uses plain SVG elements, with D3 v5 loaded but not actively used in the logic. The example demonstrates reactive state-driven updates in React for interactive graphics, with the circle centered on the pointer’s exact location.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f0a9ec39b484b1288a2edd9daa6df04?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
