'Are You Supporting the Correct Politician?'
Another great and topical (it's general election season here in Ireland) TerminusDB tutorial. This one is a little more complex, so you might want to do the 'My First Knowledge Graph' tutorial first.
Basically, this will show you how to use all the important bits of TerminusDB and the web object query language (WOQL). You can build a schema, import and clean data, run a couple of queries, and construct a killer visualization. Some links to US Congress data in there too for those that want to go a bit further.
Let me know how you get on!
