{"version":"1.0","type":"rich","title":"Fork of Mouse Follower","description":"A dark blue vertical rectangle follows the mouse cursor’s vertical position within an SVG canvas, using React’s `useState` and `useCallback` to update its `y` coordinate. The code renders a single `<rect>` element via ReactDOM, with `onMouseMove` handling pointer events. It uses static `width` and `height` constants (960×500) and fixed rectangle dimensions (30×100), with no external data—only the live mouse position.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/acc5a32862f245b5a7db61b1cc69e850?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
