{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face made of SVG shapes animates its eyebrows up and down in a loop. The demo shows how D3.js v5 selects and appends DOM elements, using `d3.select`, `d3.arc` for the mouth path, and chained `transition().duration()` calls to move the eyebrow group. A static yellow circle with black stroke forms the head, while black circles and rectangles compose the eyes and brows. The code relies on data-free hardcoded coordinates rather than a dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d2fa8e2c80e421d9fb9fb098ebf188c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
