I am looking for a free online concept mapping app similar to MindMup but without the restrictions that come with mind mapping, eg:

  • Tree heirarchy with a central node.
  • No labelled and linked edges
  • No nested sub-graphs
  • Undirected edges
  • Cannot import/Export standard graph file formats (graphml, gml)

Basically looking for a web version of yEd or VUE (Visual Understanding Environment)

Any suggestions?

Just found popplet is non-heirarchical, but does not meet the other criteria. – MachuPichu Sep 26 '13 at 1:30
