Fork of Circles with D3
This fork of the D3 circles example demonstrates a vibrant, multi-colored scatter of circles rendered on a light green SVG canvas. The code uses the d3-selection library’s `select` and data join pattern to bind an array of circle objects—each with explicit `x`, `y`, `r`, and `fill` properties—to SVG `circle` elements. It leverages method chaining with `.attr` calls to set coordinates, radius, color, and a fixed opacity, while using `container.clientWidth` and `clientHeight` to size the visualization responsively.
