This example presents a pseudo-visualization of a radar chart for Singapore across four categories: CEI, GCI, NCSI, and DDL. The code builds a radial grid with axes and category labels, then plots a single data point on each axis as an orange circle. The path connecting these points is filled in blue, though the fill and stroke are subsequently overridden to red via the `hue` module, demonstrating a deliberate layering of drawing operations. It uses D3’s `scaleLinear`, `lineRadial`, and SVG primitives like `path` and `circle`.
