Anyone got any good resources or advise regarding data visualization and finding relations between data programmaticly?

Data visualization?
MatPlotLib or if you're a java person to for javafx

@wiwe2210 for what do you need it? what's your goal?

Qliksense but I have no idea how their pricing or licensing model works.

Neo4j

check their sandboxes on the tutorial

you can't "find data relationships programatically" as some kind of a search problem, because the logic you need to implement for that inference presupposes that you know what these relationships are

for data science, Google Colab is your Jupyter Lab but hosted

For visualisation as a service, Metabase, you need a data source of course
