{"version":"1.0","type":"rich","title":"Smiley Part 1","description":"This example builds a smiley face using React and D3’s `arc` generator for the mouth, rendered as SVG. It shows a yellow circle with black stroke, two black eyes, and a curved mouth, all positioned within a fixed 960×500 viewport. Dimensions and offsets (like eye radius and mouth width) are defined as constants. The code uses `ReactDOM.render` to mount the SVG, and D3 v5’s `arc` to compute the path for the mouth’s arc, while other shapes are plain SVG circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/afaef4e45cb14f909e520fe6e3c842f7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
