{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A smiling face emoji, rendered as a single SVG circle, follows the mouse cursor across a 960 by 500 pixel canvas. The React component uses the `useState` hook to track the mouse position, which is updated on every `onMouseMove` event on the SVG element. React 16.9 handles the state-driven re-rendering, while D3 v5 is loaded but not directly used in this example. The circle’s center coordinates are bound to the current mouse position within the SVG coordinate system.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16e2f9ac6f9041aba84367b067c1a029?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
