Fork of Circles with D3
This example showcases seven colorful circles placed across a light green SVG canvas, each with distinct positions, radii, and fill colors drawn from a hardcoded data array. The visualization demonstrates D3’s data binding and the General Update Pattern through chained method calls, using `selectAll`, `data`, and `join` to create circle elements. Each circle’s `cx`, `cy`, `r`, and `fill` attributes are set from the bound data objects, with a uniform opacity applied to all shapes.
