{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by constructing a cheerful yellow smiley face from SVG primitives and animating its eyebrows. The code uses `d3.select`, `d3.append`, and `d3.arc` to build the face's circles, rectangles, and mouth path within a centered group. A `transition` with a two-second duration moves the eyebrow group up and down, creating a looping eyebrow-raising effect. The rendering is entirely SVG-based, with coordinate calculations in plain JavaScript driving the layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/028bbec324394d12b333aacf7f7b6df1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
