A geometric graph is a graph whose nodes have coordinates in a space A geometric graph is a graph whose nodes have coordinates in a space
A graph is directed if its bonds are arrows A graph is directed if its bonds are arrows
It is a multigraph if several arrows can be stacked from one node to another one It is a multigraph if several arrows can be stacked from one node to another one
Note that 'directed' does not means 'oriented': a graph is oriented if one of its nodes is its root Note that 'directed' does not means 'oriented': a graph is oriented if one of its nodes is its root
Geometric directed multigraphs have properties that make them suitable for the representation of complex phenomena, Geometric directed multigraphs have properties that make them suitable for the representation of complex phenomena,
especially those where numerous different objects and types of interactions are involved. especially those where numerous different objects and types of interactions are involved.
