Fork of Circles with D3
This example is a fork of the "Circles with D3" visualization. It displays seven semi-transparent circles, each with a unique color and position, rendered on a light green background. The code uses the D3.js library, specifically the `select` and `join` functions, to create and update SVG elements. The circles' properties—center coordinates, radius, and fill color—are defined in a static data array and applied via chained attribute methods, resulting in a static, colorful composition.
