I am having a research paper on information diffusion of Twitter - a social networking and i watched your video for demo of same problem.
Can you tell me about source code which resolve this problem?
Problem: Currently, I am coding on java but i had one problem: I want to show all Edge when i clicked node. Like on Gephi app. Please help me.
Thanks for helpful,

my workaround was installing an older version of java, other than that I have no idea

I am having an issue where I am trying to create an display a graph manually (i.e. not importing from an external file) but the nodes are not showing up. They seem just entirely invisible. I have tried changing the background color to see if they were just white on a white background, but that does not appear to be the issue. The edges show up just fine, but the nodes just don't seem to appear. My code, shown below, is mostly just pieces of the demo code from the toolkit being put together to get my desired output. Also attached is a screenshot of my display. Any help would be much appreciated. Thank you!
