{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face built from basic SVG shapes in D3 v5 demonstrates modular JavaScript composition. The code constructs circles, rectangles, and an arc-generated mouth using `d3.arc`, then positions them relative to a central group. Eyebrows animate downward and back via chained `transition().duration()` calls, simulating a blink-like motion. The face uses fixed dimensions from the SVG viewport, with all elements drawn programmatically from math constants rather than external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/61d69736d7f44029ab767b6d711d8d28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
