Graphs are data structures that model relationships between objects. Traditionally, graphs are directed, meaning that the relationships between objects have a specific direction. However, an interesting approach is the use of undirected relational graphs.
In undirected relational graphs, the relationships between objects are symmetric, meaning they are independent of direction. This approach allows for modeling more complex and subtle relationships between objects, particularly in domains such as social networks, biology, linguistics, and finance. Researchers employ advanced methods to analyze these undirected relational graphs and extract meaningful information about the structure and properties of the relationships between objects.
