{"version":"1.0","type":"rich","title":"Smiley face part I","description":"This example renders a classic smiley face as an SVG graphic using React. The face consists of a yellow circle with a black stroke for the head, two small circles for eyes, and a mouth created with a D3 arc path. The code uses ReactDOM to render the SVG elements, while D3's `arc` API defines the mouth's curved shape by specifying inner and outer radii and start and end angles. All visual elements are positioned relative to the center of a 960x500 canvas, and the rendering approach is pure SVG with D3 used for geometry computation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/429016c86a5142119f1e46b0005876d1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
