{"version":"1.0","type":"rich","title":"Smiley Face","description":"A grid of 18 smiley faces renders as SVG elements using React components. Each face is composed of a yellow circle, two eyes, and a mouth arc drawn with the d3 `arc` generator. The eyes vary randomly in radius, while the mouth and stroke width remain constant. React manages the component hierarchy, and d3 provides the `range` function to generate the repeated face instances.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f884ccff3a94e19b4abd1ddcccbddcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
