This example demonstrates how to construct a face using basic geometric shapes in D3.js, starting with a solid blue background applied to the SVG canvas. The code selects the SVG element and sets its background color using D3’s selection and style methods. It uses the vanilla D3 v7 library, with the SVG rendering approach, and the data is purely procedural—shapes and coordinates are hardcoded in the script. The example serves as a minimal template, showing how to initialize a D3 visualization in an HTML page.
