{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face rendered as an SVG animation demonstrates core D3.js DOM manipulation. The code appends geometric elements—circles for the face and eyes, rectangles for eyebrows, and a path built with `d3.arc` for the mouth—onto an SVG canvas. Chained `transition().duration()` calls animate the eyebrow group’s vertical position, moving them up and down over four seconds. Using `d3.select` to create and transform elements, this example highlights how D3 binds data-independent shapes and drives simple timeline-based motion without external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/985ecd130fa440a8867dc5cf14198c03?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
