{"version":"1.0","type":"rich","title":"Mouse follower","description":"A circle follows the mouse cursor across an SVG canvas, creating a simple interactive visual response. The React application tracks cursor position through an `onMouseMove` event handler, updating state via the `useState` and `useCallback` hooks, and renders the circle using D3 v7 within an SVG element. The circle’s center coordinates are dynamically bound to the latest mouse position, with a fixed radius of 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c436914b3e3f4657abb8073a8d3480d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
