{"version":"1.0","type":"rich","title":"Let's make a Face with D3.js","description":"A yellow SVG face is drawn with D3.js, centered in a 960×500 viewport and constructed from circles, rectangles, and an arc for the mouth. D3 transitions (`.transition().duration(2000)`) repeatedly raise and lower the eye-brow rectangles over four seconds, creating a simple animated expression. The code imports `select` and `arc` from D3 v5, uses d3.arc to build the mouth path, and sets all positions via SVG attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
