Fork of D3 Starter
This example demonstrates a minimal D3 version 6 setup for binding an array of coordinate points to SVG circles. It shows how to select an SVG container, join data using `d3.select` and `enter()`, and append circles with position and radius attributes. The visualization uses three hardcoded points rendered as identical ten-pixel-radius circles. The code uses D3’s data join pattern with `attr` callbacks, but does not include axes, scales, or interactions, serving instead as a basic starter template.
