             English: This  bubble map shows the global distribution of strontiums output in 2005 as a percentage of the top producer (China - 700,000 tonnes). 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.
