Suppose you need to chart some demographical or geographical data. Using OpenOffice.org's chart module you can present the data as a bar, pie, or even exploded donut chart. What you can't do, though, is to create a map chart that shows data distribution by continent, country, or region. To do this, you need the EuroOffice Map Chart Professional (EOMCP) extension. Unlike many other OpenOffice.org extensions, EOMCP is not free, but the price is right (it costs 9.90 EUR or about 12 USD), and there is a free trial version available.
