  <p>The application is generating the images as expected but when i try to change the layout, I am not able to get it to work . I am trying to use "Circo" or "Sfdp" instead of the "dot". I have tried the following changes but the generated image always has the exact layout as the "dot" one:</p>
  
  <p>1- I changed the line:</p>
  
  <p><code>process.StartInfo.FileName = @"C:\Program Files\Graphviz 2.21\bin\dot.exe";</code></p>
  
  <p>to:
  <code>process.StartInfo.FileName = @"C:\Program Files\Graphviz 2.21\bin\sfdp.exe";</code></p>
  
  <p>or:
  <code>process.StartInfo.FileName = @"C:\Program Files\Graphviz 2.21\bin\circo.exe";</code></p>
  
  <p>2- I added " -Kspfg"/" -Kcirco" to
  <code>process.StartInfo.Arguments = "-Tgif -Gcharset=latin1";</code></p>
  
  <p>3- I tried combining 1 and 2</p>
  
  <p>none of the above seems to work. could you please help?</p>
  
  <p>Many thanks</p>
