{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This D3.js v5 example demonstrates fundamental DOM manipulation by building a smiling face from SVG primitives, including yellow circles for the head and eyes, and rectangular eyebrows that animate upward and downward. The code constructs the face using `d3.select`, `svg.append`, and shape methods like `.attr`, while `d3.arc` generates the mouth as a path with specified inner and outer radii. A chained `transition().duration(2000)` sequence repeatedly moves the eyebrows up and down, creating a simple looping animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eb6658d26b2d44c0b7deb65ff307fce4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
