{"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. The visualization is built with React and D3 v6, using React's `useState` and `useCallback` hooks to track and update the mouse coordinates from the `onMouseMove` event. The circle is rendered as an SVG element with a fixed radius, and its `cx` and `cy` attributes are bound to the current mouse position. The example demonstrates a simple interactive pattern in a React-D3 integration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7dbb1d4482154085b74e2ca33e8395fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
