{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face rendered in SVG animates its eyebrows up and down via D3 transitions. The visualization uses `d3.select` to manipulate the SVG, `d3.arc` to construct the mouth path, and chained `transition.attr` calls to move the eyebrow rectangles over two-second durations. The code demonstrates fundamental DOM manipulation with D3 v5, importing `select` and `arc` via ES6 modules, and lays out the face using hardcoded pixel offsets for the eyes, eyebrows, and mouth within a 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/259deb8b59884b3695498ef88e600865?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
