English: This bubble map shows the global distribution of chemical tanker ships in 2006 as a percentage of the top market (Panama - 476).

This map is consistent with incomplete set of data too as long as the top producer is known. It resolves the accessibility issues faced by colour-coded maps that may not be properly rendered in old computer screens.

Data was extracted on 30th September 2007 from https://www.cia.gov/library/publications/the-world-factbook/fields/2108.html
