{"version":"1.0","type":"rich","title":"Assignment 1: 66 DOD","description":"The visualization displays a grid of 18 randomly generated smiley faces, each rendered as a yellow circle with black eyes, white pupils, and an arc-based mouth. Built with React and D3 v7, the code composes reusable components like `BackgroundCircle`, `Eyes`, and `Mouth` using SVG elements. Each face’s eye radius, pupil size, and mouth width vary via `Math.random()`, creating subtle visual diversity across the repeated layout. The `d3.arc` API generates the mouth curves, while SVG circles handle facial features within a translated coordinate system.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3e2762e1b0d5423bb5dc239be40a176c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
