Imported CSV in Gephi, but no chart displays
<p>I'm trying to visualize a set of topics, with their sub-topics, in Gephi. </p>

<p>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. </p>

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

<p>Suggestions?</p>
