{"version":"1.0","type":"rich","title":"D3","description":"A yellow circle with two smaller black eyes and an arc-shaped mouth forms a simple smiley face. The example uses D3 v5 selections to append SVG circles and a path to a fixed 900×500 viewport. The mouth is drawn with the `d3.arc()` generator, specifying inner and outer radii and an angle range covering half a circle. The code directly sets positional attributes, such as `cx`, `cy`, and `r`, to place each element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
