{"version":"1.0","type":"rich","title":"Mouse Follower with Colorful Circles","description":"A mouse follower creates an expanding circle at the cursor position, with each circle fading out and disappearing after 2 seconds. The circles use the `d3.schemePaired` color scale to generate varied stroke colors. Built with React and D3 v5, the app tracks mouse movement via React’s `onMouseMove` event and appends SVG circles using `d3.select` with a `transition()` duration of 2000ms that animates the radius and stroke opacity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dfc67cc9345241d5ae6bcbad2206a49c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
