{"version":"1.0","type":"rich","title":"data viz project","description":"A yellow smiley face on a black-outlined circle uses D3.js v5 to animate its eyebrows in a looping transition. The SVG face is centered via a translated group, with eyes placed using circles and eyebrows as rectangles. D3’s `transition` and `attr` methods move the eyebrow group up and down repeatedly, while the mouth is drawn with the `arc` generator using a half-circle path. The example demonstrates basic DOM manipulation and shape creation in D3, rendering entirely in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd91e9ba33c546eab2eac3ae678ed158?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
