U2.11

Treemaps and hierarchical area

Cards in this group · 5

  1. U2.11.1Treemaps encode shares as areas of nested rectangles
  2. U2.11.2Deep-node areas get too small to read; cap the depth
  3. U2.11.3Layout algorithms fix aspect ratios; thin strips resist comparison
  4. U2.11.4Adjacent rectangles need borders or gaps to show hierarchy
  5. U2.11.5Treemaps cannot show negatives or support cross-branch comparison
