I read this answer https://academia.stackexchange.com/a/13597/81654 and I like the idea of creating a citation map. Especially when you already have a large collection of articles and you would like to know how they relate.
There is the
relation field in biblatex, which should work for this process.
So there are actually two questions here: Is it possible to get the cited articles automagically from an article and the second question, how could you create such a map from it?
Once, I liked to create a historical overview about a topic and did this pretty much all by hand which was quite tedious.
