Let's make a face with D3.js!

This example uses D3.js v5 to construct a smiley face entirely through SVG elements in the DOM. It draws a yellow circle for the face, black circles for the eyes, and a path generated with the `d3.arc` function to form the mouth. The code demonstrates fundamental selections, attribute setting, and shape generation using APIs like `select` and `arc`. The resulting static face is rendered in an SVG container.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face from SVG shapes: a yellow circle for the head, two black circles for eyes, and an arc-generated mouth. The code uses D3 selections, `svg.append`, and the `arc` generator from the d3-shape module to construct the face. The face is static, with no interactive behavior or animations, and the rendering approach relies on SVG elements within a 960-by-500 viewport.

Shapes with SVG and CSS

This example demonstrates basic SVG shapes—circles, rectangles, lines, and paths—styled through inline attributes and CSS classes. It shows uncolored shapes, shapes with explicit fill colors, and a group with inherited fill and stroke properties. The code uses raw SVG elements within an HTML page, linked to a separate stylesheet that applies stroke width, colors, and round line joins. No JavaScript libraries are involved; rendering relies entirely on the browser’s native SVG support.
