{"version":"1.0","type":"rich","title":"Fork of Mouse Follower","description":"A circle follows the mouse cursor across a full-viewport SVG. The example demonstrates unidirectional data flow: mouse events trigger a state update, which then re-renders the visualization. Built with D3 v7, it uses `select`, `join`, and event handlers to bind the circle’s `cx` and `cy` attributes to the current cursor position. The state is managed externally and passed into the `viz` function, with `setState` triggering a re-render on each mouse move. No external data source is used; the interaction is purely based on user input.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f56486ca1ad546e48c39ff7a37692839?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
