# Graph plotting

*Graphs.jl* integrates with several other Julia packages for plotting. Here are a few examples.

## TikzGraphs.jl

Another nice graph visualization package. (TikzPictures.jl required to render/save):

```
julia> g = wheel_graph(10); t = plot(g)
julia> save(SVG("wheel10.svg"), t)
```

producing a graph like this:

## GraphPlot.jl

Another graph visualization package that is very simple to use. Compose.jl is required for most rendering functionality:

```
julia> using GraphPlot, Compose
julia> g = wheel_graph(10)
julia> draw(PNG("/tmp/wheel10.png", 16cm, 16cm), gplot(g))
```

## SGtSNEpi.jl

SGtSNEpi.jl is a high-performance software for swift embedding of a large, sparse graph into a d-dimensional space (d = 1,2,3). The Makie plotting ecosystem is used for interactive plots.

```
using GLMakie, SGtSNEpi, SNAPDatasets
GLMakie.activate!()
g = loadsnap(:as_caida)
y = sgtsnepi(g);
show_embedding(y;
A = adjacency_matrix(g), # show edges on embedding
mrk_size = 1, # control node sizes
lwd_in = 0.01, lwd_out = 0.001, # control edge widths
edge_alpha = 0.03 ) # control edge transparency
```

The above code produces the following output:

SGtSNEpi.jl enables 3D graph embedding as well. The 3D embedding of the weighted undirected graph ML*Graph/optdigits*10NN is shown below. It consists of 26,475 nodes and 53,381 edges. Nodes are colored according to labels provided with the dataset.

## GraphRecipes.jl

GraphRecipes.jl contains several recipes for plotting networks using the Plots.jl ecosystem. There are a lot of different recipes and styles to choose from, check out the examples page to see more of them.

```
using Plots, GraphRecipes
g = wheel_graph(10)
graphplot(g, curves=false)
```

## GraphMakie.jl

GraphMakie.jl is a graph plotting recipe for the Makie.jl ecosystem. It uses NetworkLayout.jl for the node placement and supports 2D and 3D plots. Check out the docs for more examples and tutorials.

```
using GLMakie, GraphMakie
using GraphMakie.NetworkLayout
g = smallgraph(:dodecahedral)
graphplot(g; layout=Stress(dim=3))
```
