In this talk, we will present the House of Graphs (https://houseofgraphs.org/), which can be a useful tool when studying graphs. The House of Graphs hosts complete lists of graphs of various graph classes, but its main feature is a searchable database of so called “interesting” graphs, which includes graphs that already occurred as extremal graphs or as counterexamples to conjectures.

We will highlight the features of the website and demonstrate how users can perform queries on this database and how they can add new interesting graphs to it.
