Some time ago I created some materials mostly for history students interested in getting started creating relatively simple visualisation of social networks using the open source software Cytoscape:

The pages include 1) basic tutorial steps (plus youtube link to screencast) 2) PDF of some slides, 3) list of terms 4) list of some orgs, software, and other online resources. I haven't updated it since 2020 so probably missing more recent things.
