{"version":"1.0","type":"rich","title":"Viz tutorial 1","description":"This example displays a grid of randomly generated smiley faces, each with varied dimensions for features like eyes, mouth, and stroke width, alongside a randomly selected background color. Built with React and D3 v7, it renders faces as SVG components, using D3’s `arc` for the mouth path and `rgb` for color generation. The code maps over an array from `d3.range` to produce 25 distinct faces, demonstrating reusable component composition and dynamic styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4e739fa194fc48c99333fc37bc22b183?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
