const Chartscii = require('chartscii');

// generate random chart data

const data = [];

for (let i = 1; i <= 20; i++) {

data.push(Math.floor(Math.random() * 1000) + 1);

}

// create chart

const chart = new Chartscii(data, {

label: 'Example Chart',

width: 500,

sort: true,

reverse: true,

color: 'pink'
