{"version":"1.0","type":"rich","title":"Smiley Face Part 4","description":"This example shows a yellow smiley face rendered as an SVG, with two circular eyes and a curved mouth drawn as an arc. The face is centered in a 960x500 viewport, using three `<circle>` elements for the head and eyes, and a `<path>` generated by D3’s `arc` function for the mouth. React manages the component structure, while D3 v7 provides the arc generator. The mouth arc uses a fixed inner and outer radius with start and end angles to create a downward curve, and the head is outlined with a thick black stroke.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/399416aa28214323878792513620ea90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
