{"version":"1.0","type":"rich","title":"Smiley Face Part II","description":"A lone black circle follows the cursor across a blank, full-window SVG canvas. Built with React, the app tracks the pointer's coordinates through the `onMouseMove` event, stores them in state with `useState`, and re-renders a single `<circle>` element at the current position. The example uses React 16.9 and ReactDOM to update the SVG in real time, demonstrating a minimal interactive visualization driven by mouse input.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf79dd953c8e4a43b5ac7f465f430bd8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
