Graphviz

Graphviz is visualization software for representing structural information like abstract graphs and networks.

Render Graphviz content in neuron by including the following HTML snippet in your head.html file (Custom JavaScript / CSS) or the zettel file (Using raw HTML in Markdown):

<script src="https://cdnjs.cloudflare.com/ajax/libs/viz.js/2.1.2/viz.js" integrity="sha512-vnRdmX8ZxbU+IhA2gLhZqXkX1neJISG10xy0iP0WauuClu3AIMknxyDjYHEpEhi8fTZPyOCWgqUCnEafDB/jVQ==" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/viz.js/2.1.2/full.render.js" integrity="sha512-1zKK2bG3QY2JaUPpfHZDUMe3dwBwFdCDwXQ01GrKSd+/l0hqPbF+aak66zYPUZtn+o2JYi1mjXAqy5mW04v3iA==" crossorigin="anonymous"></script>
<script>
window.addEventListener("load", function(){
  let viz = new Viz();
  for (let element of document.getElementsByClassName("graphviz")) {
    let parent = element.parentNode
    let pparent = parent.parentNode
    viz.renderSVGElement(element.textContent)
    .then(function(element) {
      element.setAttribute("width", "100%")
      pparent.replaceChild(element, parent)
    });
  }
});
</script>

Then include your Graphviz syntax in Markdown as follows:

```{.graphviz}
digraph G {

	subgraph cluster_0 {
		style=filled;
		color=lightgrey;
		node [style=filled,color=white];
		a0 -> a1 -> a2 -> a3;
		label = "process #1";
	}

	subgraph cluster_1 {
		node [style=filled];
		b0 -> b1 -> b2 -> b3;
		label = "process #2";
		color=blue
	}
	start -> a0;
	start -> b0;
	a1 -> b3;
	b2 -> a3;
	a3 -> a0;
	a3 -> end;
	b3 -> end;

	start [shape=Mdiamond];
	end [shape=Msquare];
}
```

When you open your generated neuron site, it will render as follows:

digraph G {

	subgraph cluster_0 {
		style=filled;
		color=lightgrey;
		node [style=filled,color=white];
		a0 -> a1 -> a2 -> a3;
		label = "process #1";
	}

	subgraph cluster_1 {
		node [style=filled];
		b0 -> b1 -> b2 -> b3;
		label = "process #2";
		color=blue
	}
	start -> a0;
	start -> b0;
	a1 -> b3;
	b2 -> a3;
	a3 -> a0;
	a3 -> end;
	b3 -> end;

	start [shape=Mdiamond];
	end [shape=Msquare];
}
