# Hypergraph drawing using Graphviz and Asymptote
|
|
|
|
## Usage
|
|
|
|
Requires Python 3 (tested with 3.9.13), [pydot](https://pypi.org/project/pydot/) (tested with 1.4.2), [Asymptote](https://asymptote.sourceforge.io/) (tested with 2.67) and LaTeX (tested with TeX Live 2021).
|
|
|
|
To render a hypergraph specified in `graph.dot`, execute the following:
|
|
```bash
|
|
cat graph.dot | dot -Tdot | python3 ./dot_hypergraph_to_asymptote.py /dev/stdin > graph.asy
|
|
asy -f png graph.asy
|
|
```
|
|
You may adjust the font size, width/height of the output and more by editing the values at the beginning of the script.
|
|
|
|
To embed the graph in a LaTeX document, set `output_latex` to true.
|
|
```latex
|
|
\usepackage[inline]{asymptote}
|
|
% ...
|
|
\begin{figure}
|
|
\centering
|
|
\input{output.asy}
|
|
\caption{...}
|
|
\label{fig:...}
|
|
\end{figure}
|
|
```
|
|
|
|
## Example
|
|
|
|
| Original graph | Asymptote rendering |
|
|
| -------------- | ------------------- |
|
|
|  |  |
|
|
|
|
`graph.dot`:
|
|
```
|
|
digraph {
|
|
edge [dir="back"];
|
|
"Node 1" -> "Node 2" [label="Edge 1"]
|
|
"Node 1" -> "Node 3" [label="Edge 1"]
|
|
"Node 3" -> "Node 4" [label="Edge 2"]
|
|
"Node 3" -> "Node 5" [label="Edge 2"]
|
|
"Node 5" -> "Node 6" [label="Edge 3"]
|
|
"Node 4" -> "Node 6" [label="Edge 3"]
|
|
"Node 2" -> "Node 7" [label="Edge 4"]
|
|
"Node 6" -> "Node 7" [label="Edge 4"]
|
|
"Node 2" -> "Node 8" [label="Edge 5"]
|
|
"Node 7" -> "Node 8" [label="Edge 5"]
|
|
}
|
|
```
