Let's make a face with D3.js!

This example demonstrates how to build a simple, expressive face using D3.js, with yellow circular head, black eyes, and a mouth drawn from an arc path. The visualization emphasizes fundamental DOM manipulation through D3’s `select` and `append` methods to create and position SVG shapes. It uses D3 v5’s `arc` API to generate the mouth’s path geometry, while hardcoded attributes like `cx`, `cy`, and `r` control the layout. The code constructs static elements only, with no animation or data input.

Lets make a face with d3.js

This example creates a minimal face using D3.js, displaying a single circle centered within an SVG canvas. The visualization focuses on simple geometric construction by selecting the SVG element and appending a circle whose radius and center coordinates are calculated from the viewport dimensions. The code uses D3’s `select` and `append` methods, along with `attr` to set the circle’s radius and position. Rendered as a static SVG, it demonstrates basic D3 shape creation without additional data or interaction.
