This example shows a collection of six colored circles scattered across a light green SVG canvas, each with varying size, position, and opacity. The code uses D3's `select` and data join to bind an array of circle objects to SVG elements, setting attributes like `cx`, `cy`, `r`, and `fill` directly. It’s a minimal starting point for building custom SVG visualizations within a Svelte component, with the data hardcoded in the JavaScript source.
