{"version":"1.0","type":"rich","title":"Mouse Follower Simple","description":"This example shows a single circle following the mouse cursor as it moves across the browser window. The visualization uses D3 v7 to create an SVG canvas sized to the viewport and appends a circle element at an initial position. Through D3's event handling, the `mousemove` listener updates the circle's `cx` and `cy` attributes based on the cursor's coordinates, producing a direct and immediate tracking effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
