This document introduces WorldMapper, an online tool that provides over 366 alternative maps of the world scaled based on different statistical measures. WorldMapper maps represent data visually rather than just showing statistics, allowing users to see what the world looks like when measured through different lenses. The document demonstrates how to access and use WorldMapper maps from an online blog, and provides an example of the type of map that could be used in an essay about global warming by showing carbon emissions by country in 2000.
