This example shows a playful array of six semi-transparent, brightly colored circles scattered across a pale green background. The visualization uses D3.js (version 7) to bind static data points—each specifying x and y coordinates, a radius, and a fill color—to SVG circle elements. The code leverages the `select` and `join` pattern to create the circles, setting their attributes directly from the bound data. The rendered result is a simple, colorful scatter-plot-like composition, demonstrating basic data binding and SVG manipulation with D3 in a Svelte environment.
