{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A small, randomly colored circle follows the mouse cursor across a full-screen SVG canvas, changing to a new random color with every mouse movement. Built with D3, the code uses `select` to append an SVG element sized to the window, a `circle` element for the follower, and the SVG `on('mousemove')` event to update the circle's `cx`, `cy`, and `fill` attributes. No data source is used; the visualization is purely interactive, with the color generated via a custom `getRandomColor` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/487e30530d73485595a56b63adfb9f81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
