{"version":"1.0","type":"rich","title":"Smiley face","description":"A yellow smiley face with black eyes, eyebrows, and an arc-shaped mouth is drawn in the center of an SVG canvas using D3.js v6. The face is constructed with D3 selections and shape generators, including `d3.arc` for the mouth and appended SVG `circle` and `rect` elements. A brief animation occurs when the eyes transition their fill color to black after a one-second delay. The graphic is rendered as static SVG with a simple transition effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1142bdd5794a4e2684d14c4933f7ffea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
