This example uses D3.js v5 and SVG to build a simple face from basic geometric shapes, including circles and rectangles. The code demonstrates how D3’s selection and data-binding capabilities can be applied to SVG elements, although the markup itself is static. The page relies on a stylesheet to color the background and define the appearance of shapes, with additional paths and lines showing stroke styling and coordinate transforms. The initial index file logs the D3 object to the console, confirming the library’s availability, while other included pages show unrelated work with cars and shape exercises.
