Fork of Circles with D3
This example shows a playful arrangement of overlapping circles, each with a distinct color and radius, set against a pale green background. The visualization uses D3 v7 to create and style SVG circle elements from a hardcoded array of data objects containing x, y, radius, and fill values. The code employs D3’s general update pattern with `selectAll` and `join` to bind this data, then chains `.attr` methods to apply each circle’s position, size, color, and a uniform opacity for a blended, layered effect.
