{"version":"1.0","type":"rich","title":"Fork of Let's make a face with D3.js!","description":"A yellow smiley face drawn with SVG circles and an arc path appears centered in a 960-by-500 viewport. The eyebrows, rendered as rectangles, repeatedly move up and down via chained `transition().duration(2000)` calls, demonstrating fundamental DOM manipulation with D3 v5. The code uses `select`, `arc`, `attr`, and `append` to build the face, with static positioning from hardcoded numeric constants rather than external data. The example is a fork of a tutorial, embedded as an interactive animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9045541bc6a74e048b0cd3424cdefcec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
