{"version":"1.0","type":"rich","title":"Trail","description":"A circle follows the mouse across a full-window SVG. The visualization uses D3 v7’s `select` to append an SVG and a single circle, then listens to `mousemove` events on the SVG to update the circle’s `cx` and `cy` attributes. The page is styled with CSS to remove margins and hide scrollbars. No data source is involved; the piece demonstrates direct mouse-driven DOM attribute updates with D3’s event handling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/88013bbf882245029c67b9a02d0e8834?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
