{"version":"1.0","type":"rich","title":"smile.js!","description":"A smiley face with animated eyebrows demonstrates basic DOM manipulation and SVG rendering in D3.js v5. The visualization constructs a red circle with a blue stroke, two eyes, rectangular eyebrows, and an arc-based mouth using D3 selection and shape-generating functions. The eyebrows move up and down via chained `transition` calls over five-second durations, showcasing D3's ability to animate SVG attributes. The code directly selects the SVG element, appends groups, and applies transforms to position facial features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/feb1584fd6874a10b01ca09f56721886?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
