title: PlantUML different layouts
body: <p>I am using PlantUML API to generate Activity Diagram. </p>
  
  <p>I have used GraphViz before and used rank parameter to define layout </p>
  
  <pre><code>rank=LR [for left to right]
  </code></pre>
  
  <p>I am trying to find similiar thing in PlantUML where I can change its orientation to "Left to Right" instead of existing layout i.e. "Top to Bottom". </p>
