Loops and Branches

A problem that can be faced when studying networks is the abundance of measures. This is particularly true for spatial networks where the combination of spatial and topological metrics contributes to the explosion of possible measures, and it is obviously worse when these networks evolve in time. In order to select the most relevant tools for characterizing these networks it is then important to have in mind a benchmark graph. We will illustrate this in the case of evolving subway networks which are spatial, time-evolving networks and whose growth can be difficult to understand without an appropriate template.
