Bug reported on https://forum.gephi.org/viewtopic.php?t=1832&p=6281#p6281

Way to reproduce:

• Start Gephi and open the Java example
• Switch to Data Labratory and select all nodes (CTRL + A)
• Right click and choose "Edit nodes"
• Set x-, y- and z-coordinate to 0
• Switch to Overview and run ForceAtlas 2
  -> all Nodes disappear (and have x- and y-coordinate set to NaN).

Doing the same thing and setting x- and y- coordinate to 1, everything works as desired.
