Let's make a face with D3.js!

This example draws a cartoon face with D3.js, composing a yellow circle for the head, two eyes, two eyebrows, and a curved mouth as a path. The code uses the `d3.select` API to target the SVG element, `append` to build shapes, and `d3.arc` to generate the mouth’s arc geometry. Positioning relies on explicit `transform` attributes, centering the face and offsetting features relative to the SVG’s dimensions. The rendering uses SVG primitives within a React starter setup, keeping the visualization simple and declarative.

Let's make a face with D3.js!

This example builds a simple yellow face in an SVG using D3.js v5 within a React framework. It shows how to compose basic geometric shapes—a circle for the head, smaller circles for eyes, rectangles for eyebrows, and a path generated with D3’s `arc` helper for the mouth—positioned relative to the SVG’s center. The code directly selects the SVG element via `select`, reads its dimensions, and applies a transform to center a group, while hardcoded offsets place facial features symmetrically. The rendering relies purely on SVG attributes, with no data binding or external datasets involved.
