{"version":"1.0","type":"rich","title":"Mouse Follwer 1","description":"A single gray circle follows the mouse cursor across the full screen, responding instantly to every movement. The visualization uses D3 v7's selection and event handling, attaching a `mousemove` listener to the SVG element. On each event, the code updates the circle's `cx` and `cy` attributes with the cursor's coordinates, logging the position to the console. The SVG fills the entire browser window via `window.innerWidth` and `window.innerHeight`, with the body reset to no margin and hidden overflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0b35c5c8b9cd42cdbb6e1c9406fcf511?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
