{"version":"1.0","type":"rich","title":"Mouse follower","description":"A black circle follows the mouse cursor across an SVG canvas, serving as a playful interactive pointer. The example is built with React and D3 v7, using React state to track mouse coordinates via an `onMouseMove` event handler. The `useState` hook stores the current `clientX` and `clientY` positions, and a `<circle>` element updates its `cx` and `cy` attributes accordingly. The SVG's width and height are fixed, and the circle has a constant radius of 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f69ac155b6ad4c539b94d446b75b1788?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
