Fork of Let's make a face with D3.js!
This example demonstrates how to build a simple animated face using D3.js v5, where a green triangular face with eyes and a curved mouth is rendered as static SVG elements. The code explicitly sets the polygon points, circle positions, and path arc for the mouth, while the D3 `select` and `append` methods handle DOM creation. The visualization focuses on fundamental DOM manipulation and attribute binding, using a fixed data-driven approach with no external data sources. The rendering relies on SVG shapes inside a centered group, with dimensions derived from the SVG element’s attributes.
