@article{Cano2015MosaicDA, title={Mosaic Drawings and Cartograms}, author={Rafael G. Cano and Kevin Buchin and Thom Castermans and Antonie Pieterse and Willem Sonke and Bettina Speckmann}, journal={Computer Graphics Forum}, year={2015}, volume={34} }

Cartograms visualize quantitative data about a set of regions such as countries or states. There are several different types of cartograms and – for some – algorithms to automatically construct them exist. We focus on mosaic cartograms: cartograms that use multiples of simple tiles – usually squares or hexagons – to represent regions. Mosaic cartograms communicate well data that consist of, or can be cast into, small integer units (for example, electorial college votes). In addition, they allow…

- Computer Science
- 2021

An empirical comparison among these three table cartogram techniques with two different real-life datasets: a meteorological weather dataset and a US State-to-State migration flow dataset shows that FastFlow and TCarto both performed well on the weather data table, however, for US State to State migration flow data, FastFlow generated concave quadrilateral faces.

### Effectiveness of Area-to-Value Legends and Grid Lines in Contiguous Area Cartograms

- Environmental ScienceArXiv
- 2022

This experiment investigated whether including an area-to-value legend (in the form of a square symbol next to the value represented by the square’s area) makes it easier for map readers to estimate magnitudes and recommended considering the cartogram’'s use case and purpose before deciding whether to include grid lines or an interactive legend.
