{"version":"1.0","type":"rich","title":"mouse follower NH","description":"A red circle follows the mouse in an inverted, mirrored motion across a full-window SVG canvas, growing in radius as the cursor moves horizontally. It uses an SVG `circle` element bound to `mousemove` events on the root `<svg>` via D3 v7's `select` and `attr` methods. The circle's `cx` and `cy` coordinates are set to negative mouse positions offset by 400, while its `r` scales with `event.x`, with `fill` hardcoded to red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c1a737901f64c81a7abac1086e0adcb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
