{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a simple smiley face in an SVG canvas using D3.js v5, with a yellow circle for the head, two eyes, and an arc-based mouth. The code demonstrates basic DOM selection and manipulation via `d3.select` and `append`, alongside geometric positioning with `attr`. A notable feature is the animated eyebrows, which move up and down repeatedly using chained `transition().duration()` calls that alternate the group’s `transform` attribute. The example uses D3’s `arc` generator to draw the mouth and relies on plain SVG elements, showing how to combine static shapes with simple programmatic animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b824782b4e049a2900bcd13e9bbc90c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
