{"version":"1.0","type":"rich","title":"Let's make face with D3.js","description":"A D3.js v5 example renders a simple smiling face as an SVG, centering a yellow circle with black stroke for the head, two dark eyes, and a curved mouth built from an arc path. The face is constructed using D3's selection and arc APIs within a transformed group, while animated eyebrows—two rectangles—loop through a two-second transition that raises and lowers them repeatedly, creating a playful, expressive motion. The visualization relies entirely on declarative SVG attributes and D3's transition system for the timed animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa175bc5eee145cbb0f127485b4fd9ac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
