A parallel coordinates chart displays nutrient amounts across US Department of Agriculture food samples, with 25 numeric axes (fat, sugars, vitamins) plus categorical axes for food group and manufacturer. Each sample is a colored polyline, sorted by food group. Rendering splits into an SVG for axes and a Canvas overlay for the 3,000+ polylines. Built with React and d3.v4, it uses d3.scalePoint, d3.scaleSqrt, d3.axisLeft/Right, and d3.brush for interactive filtering.
