{"version":"1.0","type":"rich","title":"let's make a face with D3.js !!","description":"D3.js v5 builds a smiling face from SVG primitives. The code draws a yellow head circle, two eyes, rectangular eyebrows, and a mouth arc. A two-thousand-millisecond transition animation repeatedly raises and lowers the eyebrows. The example demonstrates the `d3.select` API for SVG element selection, the `d3.arc` generator for creating the mouth path, and chained `transition` calls for basic procedural animation. The face is centered using an SVG group element transformed with computed width and height values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bcb3e0d7eb784f48b4ba4f698ddcb952?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
