{"version":"1.0","type":"rich","title":"D3 Intro Smiley Face","description":"This example shows a simple smiley face drawn entirely with SVG shapes, centered in a 960×500 viewport. It demonstrates basic D3 selections, attribute manipulation, and SVG group transformations. The code appends a yellow circle for the face, then uses two nested groups to position eye circles and line paths with `translate` transforms, relying on D3’s `select` and `append` methods. Black strokes outline the face and eye details, while CSS hides page margins and overflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
