{"version":"1.0","type":"rich","title":"mouse events","description":"An SVG circle follows the mouse cursor across a 960×500 viewport, reacting to pointer movement in real time. The visualization demonstrates mouse event handling in a React component using D3 v7’s `arc` import (though unused) and React’s `useState` and `useCallback` hooks to update the circle’s position. Rendering occurs via SVG elements within the React tree, with the `onMouseMove` event updating `clientX` and `clientY` coordinates to reposition the black circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0aac22baaf21410abf178e37c7e05b73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
