Imported CSV in Gephi, but no chart displays

Question

I'm trying to visualize a set of topics, with their sub-topics, in Gephi.

Have imported the list of topics and sub-topics into Gephi from CSV, and looking at the 'Data Laboratory', I do see those 2 columns under Source and Target.

However, when I try to visualize the data, nothing happens. On the 'Overview' page, only a blank screen appears.

Suggestions?

Answer 1

I've run into this problem before, and it usually comes from accidentally closing the "Graph" window.
To reopen it in the Overview view, click on the "Window" dropdown in the very top navbar, then click on "Graph".
