{"version":"1.0","type":"rich","title":"Mouse follower","description":"A colored circle follows the mouse across the screen, leaving a trail of fixed-size blobs whenever the left mouse button is held down. The interface includes a color picker and numeric size input to adjust the drawing properties, while a text readout shows raw or aspect-ratio–corrected coordinates. Built with React and rendered as SVG circles, the app uses `useState`, `useCallback`, `React.memo`, and window mouse event listeners to manage state and redraw efficiently.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9fa02854067f4b408d2e5437f39612cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
