Fork of Let's make a face with D3.js!
✓ Published0🌍 Public
This example demonstrates fundamental DOM manipulation with D3.js by rendering a smiley face whose eyebrows animate up and down. The face is built using SVG circles for the eyes, rectangles for the eyebrows, and a path generated with the `d3.arc()` function for the mouth. D3 transitions animate the eyebrow group’s `transform` attribute over two sequential two-second intervals. The code selects the SVG element, appends a centered group, and uses D3’s `select` and `arc` imports to construct the static and dynamic elements.
