{"version":"1.0","type":"rich","title":"smiley face","description":"This example renders a classic smiley face as an SVG graphic using React components and D3’s `arc` generator. The face consists of a yellow circle for the head, two black circles for eyes positioned symmetrically via `eyeOffsetX` and `eyeOffsetY`, and a curved path for the mouth created with `arc().innerRadius(90).outerRadius(100)` spanning from PI/2 to 3PI/2. All shapes are centered using a `<g>` transform, with the head’s radius calculated from the viewport height minus stroke width. The code imports `arc` from D3 v7 and uses ReactDOM to mount the SVG into the page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ef3964dab8c24897a6ac88e635de30c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
