Fork of Circles with D3
This example shows a collection of colored circles arranged on a mint-green background, each with a specified position, radius, and fill color. The visualization uses the D3.js library’s data join pattern to map an array of circle attributes to SVG `<circle>` elements. The code employs `select`, `selectAll`, and `attr` methods to set the SVG canvas size, circle coordinates (`cx`, `cy`), radius (`r`), and fill, with a fixed opacity value. The data is hard-coded in an array, demonstrating a data-driven approach to rendering shapes.
