{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with D3.js demonstrates fundamental DOM manipulation and animation. The code uses `d3.select` to append SVG circle and rectangle elements for the face, eyes, and eyebrows, while a D3 arc path creates the mouth. Eyebrow movement is shown through chained `transition` calls that animate the group's transform attribute over two-second durations. The yellow face with black outlines highlights basic SVG rendering and D3's data-driven approach to styling and positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c628acb2d3c4d5085aeb7bcfd31d5e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
