In gephi 0.10, how to group nodes / ungroup nodes / expand node groups ?
ie: how to do with gephi 0.10 (and not 0.7) the same as what happens between in the first 25s of the introduction video available at https://gephi.org/videos/ [1].
There is no group or ungroup menu in 0.10, and I couldn't find a layout or a plugin to have this option available.
You can't.
This feature has been removed in 0.9.0: https://github.com/gephi/gephi/releases/tag/v0.9.0
Remove ClusteringAPI from codebase. It needs a complete rewrite.
