{"version":"1.0","type":"rich","title":"Different color smiley faces","description":"Multiple smiley faces of varied sizes appear in a grid, each with differently colored eyes and a mouth drawn as an arc. The code generates 45 faces using React’s `useState` and `useCallback` hooks, while D3’s `arc()` function computes the mouth path. Each face’s position follows the mouse via an SVG `onMouseMove` handler, and face size, eye radius, and eye fill color are assigned randomly. Rendering uses SVG within React, with the `d3` library imported for arc generation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/220f50e51c8649d482fda68c393156cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
