Research direction

Start by reproducing the attached data with the NetworkLayout.sfdp and NetworkLayout.spring calls shown in the issue, including the partial-layout arguments. Trace where the StackOverflowError occurs and compare behavior for the directed and undirected graph variants; done means both layouts handle this input without overflowing the stack.

Written by the indexing model from the issue text.

Description

I have some somewhat-large graph data that I'm attempting to do partial layouts on, and I'm hitting StackOverflowErrors when I try. I'm attaching the data, and here's the code I'm using for layout:

using GraphIO.EdgeList, Graphs
using NetworkLayout
using GeometryBasics: Point
using JSON3


println("Loading data")
g = loadgraph("graph.e", EdgeListFormat())
pin = identity.(JSON3.read("pin.json"))
initialpos = identity.(JSON3.read("initialpos.json"))


println("Running layout")
# Both of the following fail
NetworkLayout.sfdp(g; pin, initialpos, iterations = 5)
NetworkLayout.spring(g; pin, initialpos, initialtemp = 3.940695496278636, iterations = 5)

data.tgz

Any thoughts? I did also try converting g to an undirected graph, but that doesn't seem to make any difference.
