This example renders a colorful spiral of 50 circles connected by thin, semi-transparent lines. Generated procedurally using trigonometric functions, the circles vary in size and hue, creating a dynamic, decorative pattern against a dark background. The visualization is built with D3 v7, using selections and data joins to efficiently draw and update both the `<circle>` and `<line>` elements. The code recalculates the layout on window resize to maintain its centered composition.
