{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example creates a smiling face using basic SVG shapes—two circles for the eyes, a larger circle for the head, and an arc for the mouth—all positioned with fixed coordinates. The code uses D3.js v5 selection methods like `svg.append` and `.attr` to build the elements, alongside the `d3.arc` generator to define the mouth’s path based on inner and outer radii and start/end angles. The SVG canvas is 960 by 500 pixels, with styling applied via an external stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b0840b9b83a424786cb6803401b103e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
