{"version":"1.0","type":"rich","title":"Mouse Follower","description":"This example demonstrates a single semi-transparent circle that follows the mouse cursor across a light green background, changing color randomly with each click. The visualization uses D3’s `mousemove` event and `d3.pointer` to update the circle’s position, while a `click` event triggers a random hex color assignment. The circle’s coordinates and fill are stored in a state object, and D3’s data join (`selectAll`/`join`) binds this state to the SVG circle element. The rendering approach relies on direct SVG manipulation via D3, with no external data source—purely interactive and state-driven.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce4b8ce4788248109d8ad81124563abd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
