Fork of Circles with D3
A colorful scatter of seven semi-transparent circles is rendered on a pale green SVG canvas. The visualization demonstrates the D3 General Update Pattern by binding an array of circle objects to SVG elements. Using `d3.select`, `data()`, and `join()`, the code sets each circle's position, radius, and fill color dynamically. The example highlights method chaining and dynamic styling with the `attr()` method, showing how D3 manages the creation and configuration of SVG shapes from JavaScript data.
