{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single dark circle tracks the cursor’s movement across a 960×500 SVG canvas. The circle’s center is repositioned directly to the mouse’s client coordinates on every move event, using React state updates triggered by the SVG’s `onMouseMove` handler. Built with React and ReactDOM, the example renders purely through SVG elements, with the circle maintaining a constant radius of 30 pixels while following the pointer smoothly across the viewport. The code initializes the circle at the canvas center before any mouse activity occurs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c161643b478847b58df0859801e64514?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
