{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js tutorial demonstrates basic DOM manipulation by constructing a yellow smiley face with animated eyebrows. The code appends SVG circles for eyes, rectangles for brows, and an arc-generated path for the mouth using `d3.arc`. A `transition` with a 2000-millisecond duration moves the eyebrows up and down repeatedly, showing chained state changes. The example relies on D3 v5 selections, `attr`, and `append` to build the face, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22c6f13330fd4441b92bba0547d1cee0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
