Drawing Networks
A Visual PrimerA node-link diagram is the easiest network picture to make and the hardest to read. This primer rebuilds a 2015 network-visualization workshop on Semiotic — every technique as a working chart — and ends with an interactive toy for thinking with a graph rather than at it.
Chapter 1What a Network Is
We visualize networks to reason about systems and relationships, not because they look cool — and the kind of network decides how hard the picture will be to read. Three families recur, in rising order of difficulty.
Networks also vary along three axes worth naming before you draw one: directionality (do edges point, or merely connect?), multipart structure (is it one kind of node, or several — people and places, say?), and edge complexity (weight, parallel edges, even negative links). Every choice below is really a choice about how to make one of those legible.
Fig. 1.1A hierarchy is the friendliest network: every node has one parent, so a tidy tree reads top-to-bottom with no ambiguity.
