{"version":"1.0","type":"rich","title":"Fork of Let's make a face with D3.js!","description":"This example builds a smiley face with D3.js v5, demonstrating fundamental DOM manipulation through SVG shapes and animated transitions. A red circle forms the head, with eyes, eyebrows, and a mouth added as separate SVG elements. The eyebrows are rectangles that move up and down via chained `transition().duration(2000)` calls, creating a simple animation loop. The code uses D3’s `select`, `arc`, and transition methods to append and animate elements, with positioning handled through explicit `attr` coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/630cf486262c42d9a9483e1dab748234?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
