You can generate SVG that can be read by LibreDraw:
neato -Gepsilon=.000000001 -Tsvg
but this does not link the objects, so if you move a node the edge does not follow, which make it much harder to post-process the drawing.
Is there an export format that can be read by LibreDraw, but that links the edges to the nodes, so individuel nodes can be moved without breaking links?
