This function detects negative cycles, highlighting one of the limitations of shortest

               path algorithms.


                         8.7.4  Visualization and Interpretation


                       Large graphs are difficult to visualize and interpret. For example, social networks with

               millions of users cannot be easily represented in a diagram. Even smaller graphs can become

               cluttered, making it hard to identify meaningful patterns without specialized visualization

               tools.


                         8.7.5  Dynamic Graphs

                       In many real-world systems, graphs are dynamic: edges and vertices change over time.

               For example, in computer networks, connections may fail or new routers may be added.

               Updating graph structures efficiently is challenging, as many algorithms assume static graphs.
               Dynamic graph algorithms are an active area of research but remain complex to implement.



                         8.7.6  Dynamic Graphs

                       Beyond theoretical limitations, practical issues also arise:

                       •  Data collection: Building accurate graphs requires reliable data, which may not
                          always be available.

                       •  Approximation: In large-scale systems, exact solutions are often replaced with
