You might scan the forum for some ideas. Here's one for you: there is a plug-in for the Data Library that will help you.
You can find it here:
https://marketplace.gephi.org/plugin/recast-column/
Once you install it, if you go to the "More Actions" menu button, you'll see a couple of options in the "Group 3" category called "Recast column," "Get standart," and "Set standart."
I've found this plug-in to be enormously valuable because it allows you use Gephi tools to assign colors, and 3-space coordinates in a layout, and then capture those using the "Get standart" function. Or, you can generate your own color values or 3-space coordinate values using your own tools or algorithms and then, using "Set standart," you can make Gephi recognize them.
Good luck!
