{"version":"1.0","type":"rich","title":"Greenface_PY","description":"Greenface_PY is an animated SVG smiley face built with D3.js v7. It shows a green circular head with blue stroke, two eyes, a curved mouth, and rectangular eyebrows that animate up and down. The example demonstrates fundamental D3 DOM manipulation and SVG rendering, using `select`, `append`, and `attr` methods to construct the face programmatically rather than relying on static markup. The eyebrow animation is achieved through chained `transition` calls with a duration of 2000 milliseconds, moving the eyebrow group vertically. The underlying data is hardcoded via dimension constants like `eyeSpacing`, `eyeRadius`, and `eyebrowWidth`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2826646650504360a4a44db46d346fbd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
