A Map That Keeps Only the Borders: One Reddit User's Topological World

In 2020, a Reddit user (xilefakamot) built a “topologist’s map of the world” that throws away every geographic property cartographers usually preserve — country shapes, sizes, and the distances between them — and keeps a single piece of information: which nations touch which. The result treats the political world as a graph, where each country is a node and every shared border is an edge, then lays that network out as compactly as possible.

The method was deliberately low-tech. Rather than running any spatial computation, the creator sketched the adjacency relationships by hand and iteratively smoothed the tangle of connections into a readable diagram. It’s a manual exercise in graph drawing more than mapmaking, and a neat illustration of how topology reduces a familiar object to its underlying connectivity.

The piece, surfaced via the MapPorn community, is a curiosity rather than a practical navigation tool — but it captures why network-first thinking is useful. Stripping away coordinates to expose pure relationships is the same abstraction that underpins how engineers reason about dependency graphs, routing, and other connectivity problems.
