[FEATURE] Fail More Clearly

[allisonletts]

When I have bigger flows, sometimes the visualiser seems not to run - but I'm just guessing that it's failed. Can the extension throw an error or information message if it's not successful?

As a first step, I'd love some sort of guidelines about when flows won't be able to render.

Oh right... This is a great point. Thank you. Are you able to provide a flow XML that causes it to fail? I had to drop the version of mermaid down as it was complaining about the number of elements, and I hope this had fixed it.

Hi @toddhalfpenny I have the same issue. This flow is not rendered: `<?xml version="1.0" encoding="UTF-8"?>
