Five circles of decreasing radius demonstrate how the stroke dash gap scales with size, using line textures as fill patterns. The example uses the textures library’s `textures.lines()` method with varying `size` parameters (from default to 10, 5, 3, and 2) to create vertical line patterns. Each circle is rendered as an SVG element with D3 v5, applying the texture URL via `.style("fill", t.url())` while maintaining a black stroke outline. The visualization highlights how pattern density changes relative to circle dimensions.
