{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face rendered in SVG uses D3.js v5 to demonstrate fundamental DOM manipulation and animation. The code draws a yellow circle with eyes, cheeks, pupils, eyebrows, and a mouth using `d3.select`, `d3.append`, and `d3.arc`. Transitions animate the pupils shifting side-to-side and the eyebrows moving up and down via `transition.attr`. The example relies on D3’s selection and transition APIs to update SVG attributes, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d312d1d380604f548693084cb4801689?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
