{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face is drawn in SVG using D3.js v5, with circular eyes, rectangular eyebrows, and an arc-based mouth. The face’s eyebrows and mouth animate over two-second transitions, moving upward and downward repeatedly. The code selects the SVG element, appends groups for positioning, and uses D3’s `arc()` generator to shape the mouth, while `transition().duration()` drives the timed movements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c78e21a0f98141b9a7f458bc4c8f0c43?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
