{"version":"1.0","type":"rich","title":"MakeFace","description":"A yellow smiley face with animated eyebrows demonstrates fundamental D3.js DOM manipulation. The face is assembled from SVG shapes—circles for the eyes, rectangles for the eyebrows, and a path drawn with the d3.arc generator for the mouth—all centered using a group transform. Two chained `.transition().duration(2000)` calls repeatedly move the entire eyebrow group up and down, creating a bobbing effect. The example uses d3.v5's `select`, `arc`, and transition methods to build and animate the composition directly in the browser.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a341787799de489fb33aa9f326ea3e8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
