Cartogram schematic sample

A schematic sample of US cartograms. A cartogram is a map visualization in which some thematic mapping variable is substituted for land area or distance. The geometry or space of the map is distorted to convey the information.

For more information about the cartogram schematic sample on IBM Accelerator Catalog, see USA cartograms visualized by number of sellers in each state.

The sample illustrates certain aspects of schematics. The main focus of each sample is not completeness of the schematic, but showing how certain things work. This sample is fully documented and tested and can be made publicly available.

For more information, see Authoring schematics - tutorial.

Cartogram schematic sample is supported as of IBM® Cognos® Analytics 11.1.7
