Highway data and map visualizations for educational use
James D. Teresco · 2012
It is often a challenge to find interesting and appropriate data sets to use as examples to demonstrate graph data structures and algorithms. Goals for the data are often conflicting. The data should include examples small enough to work through in a class example by hand, but some large enough to demonstrate important behaviors of a structure or algorithm. Data should be freely available in a convenient format and should have some real-world relevance. Visualization of the data and results computed from it is helpful.
