Visualization is a balance between letting the data speak for itself and making it look nice and attractive. This is, for sure, the textbook out there that best captures these forces, so whether you're into visualization or not, treat yourself to a copy!

Chapter 13: @jsaramak.bsky.social & @pholme.bsky.social on temporal networks of social interactions. A fascinating chapter showing why static network snapshots often miss the most important thing: the timing and order of interactions. Social networks are dynamic processes, not just fixed structures.
