No overlap: prevents the round nodes from overlapping. Optimized for big graphs. Choose speed (vs. precision), ratio (more spacing around big nodes) and margin (constant space around nodes). Great to clean a graph after another layout. NB: doesn’t manage labels.

Plugin Owner’s Notes

Adds the “Noverlap” layout in the layouts list.


  • Speed: more efficient, so expected to be quicker, but implies a lack of precision.
  • Ratio: multiplies the effective radius. Ratio=1 and nodes will just “touch” each others. Ratio=2 and nodes will separate as if they were twice as big. Ratio=1.1 adds a 10% space around nodes, which is good looking. Ratio smaller than 1 allows overlapping. NB: these explanations take in account a null margin.
  • Margin: adds the margin to the radius. Margin=0 and there is no margin. Margin=10 and nodes will separate from at least 20 pixels (twice the margin, one time for each node). A negative margin allows overlapping.

Of course the best solution is to use Margin and Ratio altogether. Which is the good setting? When we want to prevent overlap, we expect nodes to separate “well”. This means that nodes separate at least from a constant space. This is done with the “margin” parameter. But we also find that biggest nodes look better if they have a little bit more space around them that smaller nodes. This is done with the “ratio” parameter.

UPDATE 1.2 Added the grid size setting. If you experience performance issues, raise grid size.

Event Graph Layout

Description The event graph layout plugin was written to allow for the easy creation of event graphs. In an event graph the nodes represent events and the edges/arcs represent relationships between the events (e.g. causality). The layout plugin places the events in a user-specified order on the x-axis. If vertical force is activated, the plugin [...]
