{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates how D3.js can create and animate a smiley face using basic SVG shapes. The yellow circle head, eyes, eyebrows, and arc-based mouth are all built through direct DOM manipulation with `d3.select` and `.append`. The eyebrows are animated using chained `transition().duration()` calls, moving them up and down over two-second intervals. The code imports `select` and `arc` from the D3 library and relies on SVG attributes like `r`, `cx`, and `d` for rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a56a0182913a49fb85e203fed54ceca0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
