1. Social Media
Graphs depict who is connected to whom, how they interact and influence one another, as well as other relationships within the social structure. These can be used to determine how ideas propagate, what subjects become popular, how communities develop, and even who could be a good match for that particular person.
2. Epidemiology
In today’s world, disease propagation is prevalent. Understanding and limiting the spread of illnesses now depend heavily on the analysis of such graphs.
3. Traffic Management
In public transportation networks, vertices represent stops, and edges represent the connections between them. Such networks are used by several map services, including Google Maps, Bing Maps, and Apple iOS maps, to find the best routes between locations.
4. Solving Crimes
Investigations involving crime often employ graph methodology. It can help you identify the perpetrator of a significant crime by representing events as vertices on a graph and potential relationships as edges.
5. Web Page Research
Each edge indicates a connection between two sites, and each vertex represents a separate web page. To assist with the connecting procedure, algorithms are used. The graph connects websites and webpages, aiding in page ranking and allowing Google to show the best page.
