This was a doozy to figure out. Lots of examples that don't readily apply to, or work with, Azure DevOps Wiki. Credit to #1758 Huge white margins on img/png output of large diagrams

Note: I don't have access to Azure DevOps Server so I can't say whether it works there. Plus that might depend on the version you are using.
