This is excellent. I love how they have clearly illustrated how the actual details of nodes themselves can differ greatly between "network types". As a non-ex

This is excellent. I love how they have clearly illustrated how the actual details of nodes themselves can differ greatly between "network types". As a non-expert I have found this distinction is usually more buried in general descriptions, which tend to initially focus on topology and behaviour. I prefer to know those details upfront so I can then map the behaviour as an emergence as I learn about the behaviour, otherwise when reading about the behaviour it sounds more like magic.
