{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face rendered in SVG with D3.js shows animated eyebrows that move upward and downward in a looping transition. The code builds the face by appending a yellow circle for the head, two smaller circles for eyes, and a mouth path using D3's `arc` generator. Eyebrows are rectangles that animate via chained `transition().duration()` calls, shifting their y-position. The example demonstrates fundamental DOM manipulation with D3 selections and SVG attributes, using d3.select and d3.arc from the D3 v5 library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/93a7deab1eb54b50bc9c73410f22f031?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
