How to use the @vx/mock-data.shakespeare.map function in @vx/mock-data

treemapBinary,
  treemapDice,
  treemapResquarify,
  treemapSlice,
  treemapSliceDice,
} from '@vx/hierarchy';
import { shakespeare } from '@vx/mock-data';

import { scaleLinear } from '@vx/scale';

const blue = '#0373d9';
const green = '#00ff70';
const bg = '#3436b8';

const colorScale = scaleLinear({
  domain: [0, Math.max(...shakespeare.map(d => d.size || 0))],
  range: [blue, green],
});

const data = stratify()
  .id(d => d.id)
  .parentId(d => d.parent)(shakespeare)
  .sum(d => d.size || 0);

const tileMethods = {

  treemapBinary,
  treemapDice,
  treemapResquarify,
  treemapSlice,
  treemapSliceDice,
