Fork of Circles with D3
This example demonstrates a simple D3.js visualization where four circles, each with distinct positions, radii, and colors, are rendered onto a red SVG canvas. The code initializes the SVG element using D3’s `select` and `join` operations, then binds an array of circle objects to the scene. Using the D3 General Update Pattern with method chaining, it sets the `cx`, `cy`, `r`, and `fill` attributes directly from the data, highlighting how SVG shapes can be generated and styled dynamically with JavaScript.
