I am using the following code in Julia v1.6 to plot a graph:

```julia
graphplot(network1, method=:chorddiagram, markersize=3, nodeshape=:rect, linecolor=:lightgrey)

```

where network1 is a {56, 445} directed simple Int64 graph

I am getting the following error:

```julia
MethodError: no method matching get_adjacency_matrix(::SimpleDiGraph{Int64})

```

I was able to find the method get\_adjacency\_matrix in the GraphRecipes package graphs.jl, and it looks like it might be expecting to be passed either an AbstractMatrix or and AbstractVector. The output I was expecting to get from this code looks like this:
