{"version":"1.0","type":"rich","title":"Fork of Smily to Sad Face","description":"A yellow smiley face with black facial features animates its eyebrows up and down, shifting between a smiling and sad expression. The example demonstrates fundamental SVG manipulation with D3.js, using `d3.select` and `d3.arc` to construct the head and mouth. Eyebrow movement is achieved through chained `transition` calls with a 2000-millisecond duration, while circles and rectangles form the eyes and brows within nested groups. The rendering relies on an SVG container and D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e4cf306ee0b34d1087ac5958a4cb189d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
