Setup

const data = [];
const n_axis = 2000;

let i = 0;
for (x = 0; x < n_axis; x++) {
  if (x % 2) {
    continue;
  }
  for (y = 0; y < n_axis; y++) {
    if (!(y % 2)) {
      continue;
    }
    const ids = Array(((x + y) % 3) || 1)
      .fill(null)
      .map(() => i++);
    data.push([x, y, ids]);
  }
