{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"This example shows a simple smiley face drawn with D3.js v5, using SVG circles for the head and eyes and an arc-generated path for the mouth. The face is constructed with hardcoded dimensions and positions, including an eye spacing of 100 pixels and a mouth arc spanning from π/2 to 3π/2. The code imports `select` and `arc` from the D3 library, appends SVG elements to a 960×500 canvas, and uses the `arc` generator with inner and outer radii to create the mouth shape. No external data is loaded; the design is purely programmatic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4a88004d94d44daa1c41fbbfd327455?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
