Description

Would it be possible for the cartogram to scale features absolutely as well as relatively? Only the latter seems to occur at the moment that is, total area seems to preserved as U.S. states are scaled against one another. For example, with the dataset being presented in the attached image, the US should being nearly twice as large as it actually is, yet the cartogram is roughly the same size as the unmodified map. usef2010cartogram-scalingref

Contributor guide

Research direction
Understand the current cartogram scaling implementation in TopoJSON and modify to support absolute scaling. Look for the function that performs area scaling and add a parameter to control relative vs absolute scaling.
