There's a set of slides in the middle of this presentation (24-30) that really illustrate how graph analysis is used to present data in a way that is equally compelling, and more useful, than a typical narration. Overall, the message of the presentation is that graph analysis is most useful for cases where we have loosely connected data, where we have simplistic and disconnected data models, where the data models can’t keep pace with market dynamic, and where the data models are too abstract. Graphs make these cases concrete and intelligible. A narrative would do the same, but in an entirely arbitrary and often misleading way.
