This visualization displays nutritional data for two groups, "Before" and "After," using a multi-axis radar chart with 20 nutrient categories. The chart uses D3 v4 APIs such as `d3.lineRadial()`, `d3.curveLinearClosed`, and `d3.scaleLinear()` to draw concentric level lines, radial axes, and percentage labels. Each group is rendered as a semi-transparent, colored polygon with circles at data points, accompanied by an SVG legend. The hard-coded values, identical across both groups, suggest a template for comparing dietary intake profiles.
