This pseudo visualization demonstrates a radar chart for a single data point, Singapore, with values across four categories: CEI, GCI, NCSI, and DDL. The example shows how modular code functions in `d3.lineRadial` to draw the blue radar path, `circle` elements to mark data points, and SVG `line` and `text` elements to render the gray axes and category labels. The `d3.scaleLinear` maps values from 0 to 25 across five levels. The hue function redundantly adds a red fill, showcasing the composition of overlapping shapes in a modular structure.
