Treemap
There are a number of ways to make treemaps, but the interactive software
by the University of Maryland Human-Computer Interaction Lab is the original
and is free to use. As you saw in Chapter 3, “Representing Data,” treemaps
(developed by Ben Shneiderman in 1991) are useful for exploring hierarchical
data in a small space. The Hive Group also develops and maintains a commer-
cial version for businesses. See more at: http://www.cs.umd.edu/hcil/treemap/.
TileMill
Not that long ago, custom maps used to be hard to make and highly techni-
cal, but various programs have made it relatively straightforward to design
maps to your liking, for your needs, and with your data. TileMill, by mapping
platform MapBox, is open source desktop software available for Windows,
OS X, and Ubuntu. Just download and install the program, and then load a
shapefile, as shown in Figure 7-3.
