{"version":"1.0","type":"rich","title":"Making a bar chart","description":"A smiley face rendered in SVG shows animated eyebrows that move up and down. The D3.js code uses `select` and `append` to build circles for the face and eyes, rectangles for eyebrows, and a path with an arc for the mouth. A `transition` with a 2000-millisecond duration animates the eyebrow group’s transform, shifting it vertically and back. The example demonstrates fundamental DOM manipulation with D3 v5, using static SVG attributes and chained transitions to create a simple looping animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4e8208e84a364db788872f0168393341?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
