{"version":"1.0","type":"rich","title":"Hellow World","description":"A grid of randomly generated smiley faces, each a yellow circle with eyes and a smiling mouth, illustrates the composition of SVG graphics through modular React components. The faces vary in stroke width, eye placement, and mouth size, created using `d3.arc` for the mouth path and `d3.range` for repetition. The rendering relies on React’s component system and ES6 modules.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f0073fac63c54a14a5cef09d34a986c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
