{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face appears in an SVG, built entirely through D3.js v5 selections and DOM manipulation. The face includes a head, two eyes, and a mouth drawn with the `d3.arc()` path generator. The eyebrows, rendered as rectangles, animate continuously via chained `transition` calls, moving up and then back over 2-second intervals. The example demonstrates fundamental SVG element creation, coordinate transforms, and data-driven attribute updates using D3's `select`, `append`, and `attr` methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38ec5f706ac74197a39bdfb24e7e9a49?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
