{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circular SVG marker tracks the cursor's position in real time across a full-browser canvas. The visualization uses React's `useState` and `useCallback` hooks to manage mouse coordinates, with an `onMouseMove` event handler updating a circle element centered at the pointer. Built with React 16.9 and rendered as SVG, the example demonstrates a minimal interactive pattern where the circle's `cx` and `cy` attributes are bound to the current mouse position, creating a responsive follower effect without additional data sources or complex D3 logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/659528a9f4d64ea6b434b3dab0b2ee00?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
