📊 Visualization
🧰 What the app does
- Decompose revenue by tax type: direct taxes, indirect taxes, taxes on international trade, VAT, and the remaining sources.
- Follow each component over time: see how the share of every tax type in GDP has moved, rather than reading a single year.
- Filter by region and country: compare fiscal structures across groups of economies, or drill down to one.
- Exportable tables behind each view.
