{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of Mouse Follower Simple","description":"A single gray circle follows the mouse cursor across a full-screen SVG canvas, creating a direct and immediate visual link between pointer movement and graphical output. The example uses d3-selection to append an SVG circle and attach a `mousemove` event listener to the SVG element, updating the circle’s `cx` and `cy` attributes with the event’s x and y coordinates. Rendered in a browser via a minimal HTML page, it demonstrates fundamental D3 v7 selection, event handling, and attribute manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cfc213fc36ae4f53b661135c3e5e321a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
