Currently, network graphs do not allow to customise edges and nodes in a similar fashion than the other visualisations (e.g. no customised colour theme for categories, "colour by" includes a set of hardly distinguishable shades of green and purple). Furthermore, network graphs tend to become unstable (lead to crashes) when X and Y axis are introduced in a mapping table. Increasing stability and allowing to customise the graph as with all the other visualisations would significantly increase usability of network graphs.
