Power graphs provide an innovative way to visualise and analyse the algebraic structure of finite groups. In a power graph, the elements of a finite group serve as vertices, and an edge is drawn ...

Scatter graphs show how two sets of data are related to each other. Data points are plotted on a graph and then a line of best fit is drawn to show the overall trend, close trendThe overall ...

Additionally, research on planar graphs has yielded new insights into the anti-Ramsey numbers for paths and cycles, thereby bridging classical graph theory with geometric constraints [3].

Combined graphs Sometimes, graphs may be combined together. For example, a climate graph and a flood hydrograph both present data using a bar chart and a line graph in a single graph.

But the concept dates back to the 18th century, when Leonhard Euler laid the foundation of graph theory. Euler was a Swiss scientist and engineer whose solution to the Seven Bridges of Königsberg ...

The field of graph theory has been around since 1736, when Leonhard Euler published an article on the subject of the Seven Bridges of Königsberg (in Prussia, today’s Kaliningrad in Russia).

Graph theory, a nearly 300-year-old discipline considered an element of discrete mathematics, is used to model many types of relationships and processes in physical, biological, social and information ...

This paper summarizes the known results on graphs with smallest eigenvalue around -2, and completes the theory by proving a number of new results, giving comprehensive tables of the finitely many ...

Graph theory has a lot to say about how phenomena can grow, such as the spread of infectious diseases. There are different graphs, or networks, of relations, and they can affect things such as the ...
