Extensions and generalizations of graphs

Voltage graph

In graph theory, a voltage graph is a directed graph whose edges are labelled invertibly by elements of a group. It is formally identical to a gain graph, but it is generally used in topological graph theory as a concise way to specify another graph called the derived graph of the voltage graph. Typical choices of the groups used for voltage graphs include the two-element group ℤ2 (for defining the bipartite double cover of a graph), free groups (for defining the universal cover of a graph), d-dimensional integer lattices ℤd (viewed as a group under vector addition, for defining periodic structures in d-dimensional Euclidean space), and finite cyclic groups ℤn for n > 2. When Π is a cyclic group, the voltage graph may be called a cyclic-voltage graph. (Wikipedia).

Linear graphs for Physics and Maths -: from fizzics.org

Graphs are an important visual means of proving and displaying numerical connections. Linear or straight line graphs are produced for example when plotting current against PD for a fixed resistance, distance against time for a given speed and the energy of a photon plotted against frequenc
