Parallel Coordinates Recipe

Minimal flow

Runnable: install ggaction and provide the named data array as plain row objects.

import { chart } from "ggaction";

const program = chart()
  .createCanvas({ margin: { top: 80, right: 140, bottom: 60, left: 70 } })
  .createData({ values: cars })
  .createParallelCoordinates({
    dimensions: [
      "Miles_per_Gallon",
      "Horsepower",
      "Weight_in_lbs",
      "Acceleration"
    ],
    color: "Origin"
  });

cars is an array of plain row objects. Every eligible row becomes one open path across the ordered dimensions.

You must decide

• At least two unique dimension fields in axis order
• An optional unique row key
• Whether missing values break a path, drop the row, or raise an error

The library infers

• One Parallel coordinate and one local scale per dimension
• Quantitative or ordinal dimension types from unambiguous values
• Dimension axes and an applicable categorical legend
