{"version":"1.0","type":"rich","title":"Shapes with SCG and CSS","description":"This example demonstrates how to create a smiling face using basic SVG shapes—circles for the eyes and an arc for the mouth—positioned within a 960x500 viewport. The code uses D3 v5’s `select` and `arc` functions to append elements to the SVG, while CSS styles handle page margins and a red highlighted text class. The arc is generated using inner and outer radii with a start angle of zero and an end angle of π, producing a half-circle smile centered in the composition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ecba5f642c5419a985fd016fa99ccdb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
