{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A mouse-controlled circle follows the cursor across an SVG canvas, changing its fill color randomly with every mouse movement. Built with React and D3, the component tracks client coordinates through an `onMouseMove` handler and updates the circle’s `cx`, `cy`, and `fill` attributes via state. The example demonstrates reactive SVG rendering with D3’s `rgb` color generator.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8841d26c6e554e7f8abc3476e9c690fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
