- 02Treemaps excel over pie charts for accounting general ledgers because 8–12 cost centers fit comfortably with full text labels and percentages inside each block.
- 03Compare vendor SaaS spend and cloud infrastructure tiles against headcount payroll at a single glance.
- 04Use the Braun Monochrome or Architectural Standard palette for clean board memo aesthetics.
Frequently Asked Questions
When should I use an Expense Treemap vs. a Budget Donut Chart?+
Use a Budget Donut Chart for 4–6 top-level departments, and use an Expense Treemap when breaking down 7–15 detailed general ledger cost lines.
Are percentage shares shown automatically inside the tiles?+
Yes, when Data Labels are enabled, every sufficiently sized tile displays its category label, dollar value, and exact percentage of total spend.
Can I paste directly from QuickBooks, Xero, or NetSuite exports?+
Yes, copy any two-column Category + Amount range from your spreadsheet export and paste it into the CSV/TSV Workbench.
