{"version":"1.0","type":"rich","title":"Mouse follower","description":"A circle tracks the mouse cursor across an SVG canvas, reacting instantly to movement. The visualization demonstrates state management in React, using the `useState` hook to store cursor coordinates and `useCallback` to optimize the mouse-move handler. The SVG circle updates its `cx` and `cy` attributes based on those coordinates, rendered via ReactDOM. The example uses D3.js v7 only for its bundled build, while the core interaction is purely React-driven.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95e68facfaab425f801e452a3e87297c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
