Overview
Use the OPF world chart type to describe geographic categories and their values, such as revenue by state or country. This authors the data; it does not guarantee a native geographic map. The pptx.dev generator currently exports this chart as a text summary. Other exporters and target applications may use a different fallback.
One Map Chart Type
world is OPF’s geographic chart identifier. Put place names in the data’s category columns and values in its rows; there are no separate chart types for US states, UK regions, Canadian provinces or Australian states. Place names alone do not guarantee geographic matching or automatic zoom. Check the generated presentation in your target application before relying on a map.

When to Use Map Charts
| Use case | Map type |
|---|---|
| International sales | world |
| US market analysis | world, with US states in the category column |
| UK regional strategy | world, with UK regions in the category column |
| Canadian market | world, with Canadian places in the category column |
| Australian operations | world, with Australian places in the category column |
Tips for Map Charts
- Include only regions with data. Empty regions display as neutral — no need to include zero values.
- Use 5-10 data points. Too many regions makes the chart hard to read at presentation scale.
- Pair with a table or bar chart on the next slide for exact values. Maps are good for patterns, not precision.
- Choose color schemes carefully. Choose a scheme with enough contrast for the labels and values.
