Hi,
I have this graph
The picture shows that some nodes, the center of each hexagon for example, and some edges are behind the shapes.
In the dot file ( and I don’t know if that matters ) the statements for the centers are always after the statements of the corresponding hexagon.
But the SVG output file does not have the same order and I guess that the rendering order is based on the document order.
How could I have the centers and the edges in the front ?
Thanks
First: really nice graph!
Yes, the order of the input matters.
Also, the subgraphs that were defined with the radial edges caused problems.
I reordered the input, eliminated redundant definition of center_frame, and replaced all the radial edges with 3 long edges.

Thanks for your kind comment !
I think that I understood the behavior.
The fact that the “center_frame” node statement was specify before some hexagons seems to be the origin of the problem.
Indeed, as center_frame is the origin of each edge, the edge itself is behind and as the edge itself is behind the end node is behind too. ( it’s just a guess )
Anyway, I simplified the graph to highlight that.
