1. A method comprising: generating a network topology graph comprising a first set of one or more graph nodes and a second set of one or more graph nodes, wherein the graph nodes represent network elements; receiving, at a computing device having a touch-sensitive display, touch input that selects and drags the first set on the network topology graph; in response to the touch input, adding or removing a graphical representation of a connection between the first set and the second set on the network topology graph; wherein the method is performed by one or more computing devices.
