{"version":"1.0","type":"rich","title":"Smiley face with D3","description":"This example shows a classic smiley face drawn as a yellow circle with black eyes and a curved mouth on a transparent SVG canvas. The code uses D3 v5’s `select`, `append`, and `attr` methods to create SVG circles for the face and eyes, while the smile is rendered as a path generated by the `arc` generator with specified inner and outer radii and start/end angles. The face is centered within a 960×500 SVG element, and eye spacing and offset are controlled by numeric variables. No external data is loaded; all shapes are procedurally generated.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9ea646fa576f476983578c66020e1af3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
