{"version":"1.0","type":"rich","title":"Let's make a face with D3","description":"A face made of SVG shapes—a circle head, elliptical eyes, rectangular eyebrows, and an arc-based mouth—is drawn in the center of a 960×500 viewport using D3 v5 selections and the `arc` generator. The face is statically rendered with fixed pixel positions and colors, while the eyebrows animate upward and back down over four seconds via chained `transition().duration(2000)` calls, demonstrating D3's built-in animation for SVG attribute interpolation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a656b18364b480292e695b088290910?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
