{"version":"1.0","type":"rich","title":"Smily face part I","description":"A smiling face made of SVG circles tracks the mouse cursor across a yellow background. The interactive visualization renders a black circular pupil that follows the pointer, while two white eye outlines and a grey-bordered yellow face remain fixed. Built with React and D3.js v6, the app uses React's `useState` and `useCallback` hooks to handle mouse movement events, updating the circle's `cx` and `cy` attributes. The SVG output is generated by React components for the background, eyes, and moving pupil.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6ed0aa871cea43ab950d1578081f9e3e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
