{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"A yellow circle with black-outlined features forms a smiling face. The D3.js code builds the face using SVG primitives: a circle for the head, two circles for eyes, and arcs from `d3.arc()` for eyebrows and a mouth. An animation sequence uses chained `transition()` calls with 1000-millisecond durations to repeatedly raise and lower the eyebrows, creating a winking or surprised expression. The example demonstrates basic SVG drawing and simple timeline-based animation in D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8dd10b12af834a68b260fa541d3c4ca8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
