A 4,000-Word Visual Guide to Graph Theory, From City Traffic to Shortest Paths
TivadarDanka · x · 2026-11-11
Tivadar Danka published a 4,000-word beginner-friendly tutorial, Graph Theory for Visual Learners, on The Palindrome.
- It opens with his hometown split by a river and two bridges: strip the map down to intersections (nodes) and streets (edges), and traffic becomes a walk on a graph — close one bridge and flow shifts; overload it and the city freezes.
- He shows how highlighting streets that appear on many shortest paths reveals a city's traffic arteries, a concrete illustration of concepts like betweenness centrality.
- The post also promotes his Mathematics of Machine Learning book (33% off on Amazon) and a $100/year paid subscription with deep dives like Matrices and Graphs and vectorization in theory + practice.
