Fork of Circles with D3 Sprice
This example demonstrates a dynamic SVG visualization that randomly generates colorful circles, rectangles, and ellipses on a light green background. The code uses D3.js v7 with the `select`, `join`, and `append` APIs to create and style SVG elements based on randomly generated data arrays. Each shape receives random positions, sizes, and colors from a palette of six vibrant hues, with opacity set to 70%. The visualization regenerates its layout each time the `main` function is called, showcasing D3's data-binding and method chaining patterns for creating basic geometric compositions.
