PlainChart

A text-based, no-dependencies, open-source charting utility in JavaScript. It is inspired by the Python library plainchart.

Usage

import PlainChart from "@betterthings/plainchart";
const chart = new PlainChart([3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 9]);
console.log(chart.render());

Take a look at example.mjs to see how to generate something like this:

         ××××××××                                          ××××××××
      ×××        ×××                                    ×××        ×××
    ××              ××                                ××              ××
  ××                  ××                            ××                  ××
