    arr.push({
      a: Math.random() * 10,
      d: 'Row ' + i,
      cat: cats[Math.floor(Math.random() * 3)],
      cat2: cats[Math.floor(Math.random() * 3)]

Advanced Usage Example

// arr from before
viewof selection = {
  const b = builder(data);
  b.column(
    LineUpJS.buildStringColumn('d')
      .label('Label')
      .width(100)
  )
    .column(LineUpJS.buildCategoricalColumn('cat', cats).color('green'))
    .column(LineUpJS.buildCategoricalColumn('cat2', cats).color('blue'))
    .column(LineUpJS.buildNumberColumn('a', [0, 10]).color('blue'));

  // and two rankings
  const ranking = LineUpJS.buildRanking()
    .supportTypes()
    .allColumns() // add all columns
    .impose('a+cat', 'a', 'cat2') // create composite column
    .groupBy('cat')
    .sortBy('a', 'desc');

  b.defaultRanking().ranking(ranking);
  return b.build();
