{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example shows a smiley face built with basic SVG shapes in D3.js, including a yellow circle for the head, two eyes, and an arc-based mouth. The eyebrows animate vertically in a looping transition using `transition()` and `attr()` to move a rectangle group, demonstrating fundamental DOM manipulation with `d3.select` and `d3.arc`. The code uses D3 v5 and renders entirely in SVG, with the face centered using SVG transform attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fc24965aa17b46cdbb3d524cf59f3e41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
