{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with D3.js demonstrates fundamental DOM manipulation through a yellow circle, two eyes, animated eyebrows, and a mouth. The eyebrows transition up and down using D3's `transition().duration()`, while shapes are created with `select`, `append`, and `attr` calls. The mouth uses the `d3.arc()` path generator with specified inner and outer radii and angles. SVG rendering displays the face centered via a translated `<g>` group, with dimensions derived from the SVG attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4400f33346ec4ad3ad4bbcf63437438c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
