A collection of hand-drawn SVG shapes and paths demonstrates how to style vector graphics with D3 v5. The example renders a static composition of lines and curved paths on a 960×500 SVG canvas, using the `select` method to target the SVG element. CSS classes define stroke properties, including color, width, and round line caps and joins, while the `overflow: hidden` body style trims the viewport. The code focuses on basic SVG styling and selection patterns rather than data binding or dynamic updates.
