{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates basic DOM manipulation with D3.js by arranging red rectangles into a grid and positioning them within an SVG canvas. The code uses D3’s `select` and data joins (`selectAll().data().enter().append()`) to generate groups and rectangles based on calculated coordinates. It explicitly references `d3.arc` (imported but unused), while the visible rendering relies on SVG `rect` elements positioned via transform attributes. The layout logic computes row and column counts from a given number of replicas, though the current implementation produces a simple static grid rather than an animated face.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/177fc1cd1954466289c95f5f209f9a13?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
