The field of graph theory has been around since 1736, when Leonhard Euler published an article on the subject of the Seven Bridges of Königsberg (in Prussia, today’s Kaliningrad in Russia).

The study of such graphs is called graph theory. Engineers need to find planarity in a graph when, for example, they are designing a computer chip without a crossed wire.

Graph theory suggests COVID-19 might be a ‘small world’ after all ... For the vast majority of entities in a graph, such as, for example, the people who could potentially be infected, ...

Where Graph Theory Meets The Road: The Algorithms Behind Route Planning. April 4, 2024 by Maya Posch 33 Comments . Back in the hazy olden days of the pre-2000s, navigating between two locations ...

Refining with colors. Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.

As you can see in the image above, my visualization was simpler with only 34 nodes. My little innovation on Shipper's code is to show the number of the threshold increment (i.e., 22 of 34).
