{"version":"1.0","type":"rich","title":"Exercise 1","description":"A simple yellow smiley face rendered as an SVG, with black outlined circular head, two eyes, an elliptical nose, and a curved mouth arc. The visualization is built using React for component structure and D3 v7’s `arc` generator to define the mouth path. The SVG is centered on a 960×500 canvas, with all shapes positioned relative to the center point, and the mouth arc spans a half-circle using specified inner and outer radii.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40fef31e997a4c50a16ca5ce4327ad14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
