The trick to get the graph you described is to use two subgraphs and link from one to the other. The invisible edges in "details" are what keep the notes aligned.

<pre><code>digraph {
 rankdir="LR";

 subgraph steps {
 rank="same";
 "Step1" -&gt; "Step2" -&gt; "Step3";
 }

 subgraph details {
 rank="same";
 edge[style="invisible",dir="none"];
 "note1" -&gt; "note2" -&gt; "note3" -&gt; "note4";
 }

 "Step2" -&gt; "note1";
 "Step2" -&gt; "note2";
 "Step2" -&gt; "note3";
 "Step2" -&gt; "note4";
}
</code></pre>

The result is:

Here's as simple as it gets - just use the <code>group</code> attribute to have graphviz prefer straight 
edges:

<pre><code>digraph {
 node[group=a, fontname="Arial", fontsize=14];
 "Step1" -&gt; "Step2" -&gt; "Step3";

 node[group=""];
 "Step2" -&gt; "note1";
 "Step2" -&gt; "note2";
 "Step2" -&gt; "note3";
 "Step2" -&gt; "note4";
}
</code></pre>

By grouping the Step nodes into a clustered subgraph, the output is as follows:

<pre><code>digraph {

 "Step1" -&gt; "Step2" -&gt; "Step3";
 }

 subgraph cluster_1 {

<code>color=invis</code> removes the border that would otherwise be drawn around the cluster

rankdir doesn't work directly in the subgraph, but if you add another set of curly braces - whatever that's called - rankdir works:

<pre><code>digraph {
 "Step1" -&gt; "Step2" -&gt; "Step3";

 subgraph step2detail {
 {
 "Step2" -&gt; "note1";
 "Step2" -&gt; "note2";
 "Step2" -&gt; "note3";
 "Step2" -&gt; "note4";
 rankdir=TB
 rank=same
 }
 }
}
</code></pre>

Use the command: rankdir=LR;

<pre><code>digraph {

 subgraph step2detail {
 "Step2" -&gt; "note1";

I have a graph file like this:

<pre><code>digraph {
 "Step1" -&gt; "Step2" -&gt; "Step3";

 subgraph step2detail {
 "Step2" -&gt; "note1";
 "Step2" -&gt; "note2";
 "Step2" -&gt; "note3";
 "Step2" -&gt; "note4";
 rankdir=TB
 }
}
</code></pre>

I want the subgraph step2detail to hang off to the right of 'Step2'.

Right now it looks like this:

I want Step1, Step2 and Step3 to all be vertically under each other and in 1 column.
