{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example draws a cheerful smiley face as an SVG, with yellow circular head, black eyes, and a curved mouth arc. It demonstrates D3.js v5 selection and shape generation using `d3.select`, `d3.arc`, and attribute binding. The right eyebrow animates via chained `transition().duration()` calls, moving downward and back over two seconds. The 960×500 SVG canvas is centered with a `g` group transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0610526fdccf432da0eaff94cf70d4e5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
