Fork of Fork of Circles with D3
This example demonstrates creating colorful, overlapping circles on an SVG canvas using D3.js, with each circle’s position, size, and color defined by a static data array. The visualization shows how the D3 general update pattern and method chaining bind data to SVG circle elements, setting attributes like `cx`, `cy`, `r`, and `fill` for each data point. The code uses `d3.select` and `join` to manage the SVG and circle elements, with dimensions derived from the container’s client width and height, and a fixed opacity applied to all circles.
