When choosing "Save" in a Maven Dependencies diagram (powered by yFiles), the file extension saved is ".uml", and is an XML file with the following format:
<node x="111" y="222">...</node>
<settings layout="Hierarchic Group" zoom="0.02059732234809475" x="8028.299999999999" y="12613.324999999999" />
It seems to only be opened in IntelliJ, which is limiting since yFiles is able to export in many more portable formats that could be used in other graphing/UML tools (including yEd, which is free).
Can anyone offer insight on if this is usable in other applications or is it just usable within IntelliJ? I think it would be pretty straightforward to enable the other export options in yFiles to allow portability with these diagrams.
