{"version":"1.0","type":"rich","title":"Hello VizHub!","description":"A simple SVG smiley face is drawn using D3 v5, centered in a 960-by-500 viewport. The code creates a yellow circle with black stroke for the head, adds two eyes with rectangular eyebrows, and a mouth using a D3 `arc()` path. Layout is driven by manual transforms and numeric constants rather than data. The static example runs in a dark-themed page with Ubuntu font, highlighting basic D3 shape construction and SVG coordinate manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8e372133d8bf4d1cbe1084626e79dabd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
