Graphs can be a powerful way to represent relationships between data, but they are also a very abstract concept, which means that they run the danger of meaning something only to the creator of the graph. Often, simply showing the structure of the data says very little about what it actually means, even
though it’s a perfectly accurate means of representing the data. Everything looks like a graph, but almost nothing should
ever be drawn as one. Ben Fry in ‘Visualizing Data’
