Using a graph can be a good way of encoding lots of information. The graph, as a structure, should particularly be used when you have relationships within the data, which the graph can represent with edges. The edges are the essential component of the graph that makes it different from storing data in a tabular format. The graph structure can cause issues when running cluster methods, as clustering methods are not typically made to support taking in node information and edge information simultaneously. This tutorial will talk about how you can combine the node and edge information to run traditional node attribute-based clustering methods like KMeans or DBScan. Node attribute-based clustering refers to methods that solely take in a node embedding (for example, an (x,y) coordinate pair, which can be used to represent a node in 2D space).
