{"version":"1.0","type":"rich","title":"Mouse Follower That Changes Color","description":"A circle follows the mouse cursor across a full-screen SVG canvas, changing its fill color to a random RGB value on each click. The visualization demonstrates unidirectional data flow with a state object managed by `setState`, while D3 v7 selections and the `join` pattern handle SVG rendering. Mouse position events trigger state updates through `svg.on('mousemove')`, and color changes use `svg.on('click')` with random `rgb()` generation. The example uses d3.select and d3's data join to bind single elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bc14428827140ff85db657d13e961f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
