{"version":"1.0","type":"rich","title":"circle following cursor","description":"A yellow circle with a black outline follows the cursor across a blank SVG canvas. The circle’s position is updated on mouse movement using React state and the `onMouseMove` event handler. The visualization is built with React 17 and D3 v7, rendering SVG elements directly. The code uses `useState` and `useCallback` to track and set cursor coordinates, demonstrating interactive data-driven updates without any external dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b1efebad93ca4719a1cb13279d29bfe3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
