{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A static SVG smiley face is drawn with D3.js using primitive shapes: circles for the face and eyes, rectangles for the eyebrows, and an arc for the mouth. The example demonstrates DOM manipulation and chained transitions, as the code applies a two-second `transition().duration(2000)` to animate the eyebrows moving up and then back down. All elements are positioned relative to the SVG center via a `g` transform, showing fundamental D3 selection and attribute methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0ddaf2256b544757afb29ccab3d835f4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
