{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiling face built entirely with D3.js SVG elements animates its eyebrows upward and downward in a repeating loop. The example demonstrates fundamental DOM manipulation through D3 selections, appending circles for the face and eyes, rectangles for eyebrows, and an arc-generated path for the mouth. Using `d3.select`, `transition().duration()`, and the `arc()` generator, it shows how to bind data from a CSV file and apply chained transitions to transform SVG attributes. The face is centered via a group transform, with the population dataset loaded from `data.csv` though not visually mapped to the graphic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1b6dc5f08b741a8b07e468b12328c49?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
