{"version":"1.0","type":"rich","title":"Mouse Follower Simple","description":"A simple interactive visualization renders a circle that follows the mouse cursor. The circle grows in radius as the user moves the mouse faster, measured via the `event.movementX` and `event.movementY` properties, with its size capped at 100 pixels. The example uses D3 v7's selection and data join methods (`select`, `selectAll`, `join`) to bind SVG elements, updating position and radius on each `mousemove` event. The circle is styled with a transparent fill and a black stroke, demonstrating dynamic SVG updates with D3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f36a5c7577f84880bb97019782cd4206?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
