{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle tracks the cursor across a full-screen SVG canvas. Each mouse movement updates the circle’s center coordinates via a state object and a custom `setState` callback. The visualization uses d3.v7’s `select` API to bind SVG elements and handle `mousemove` events, while `join` synchronizes the circle’s `cx` and `cy` attributes. The canvas resizes to the browser window dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c0230ae36ba4301a3d506ac83398fb5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
