{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face with black outlines is built from SVG shapes, including circles for eyes and a mouth drawn as an arc path. The animation shows the eyebrows, two rectangles, moving upward and back down via chained `transition().duration()` calls. D3.js v5 selects the SVG element and manipulates attributes like `cx`, `r`, and `transform` using `select` and `append`. The code uses D3's `arc` generator to construct the mouth, and all positioning is centered within a 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9451f15664e468bb1f90d0909721999?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
