graphviz was not found on the system

[azizur]

During installation (on MacOS) I am getting this message:
graphviz was not found on the system. Downloading vizjs instead. See http://plantuml.com/vizjs. This may take a few minutes.

This means it should work regardless of graphviz installed or not because vizjs is being installed. However, I am getting an error in the generated output site.

The graphviz requirement is not listed as a dependency. It would be useful to have this documented for new starters.

On Mac OS, it's simple homebrew command to install it:
brew install graphviz

[azizur]

I can confirm after installing graphviz via brew, it worked as expected.

Indeed, I need to update the docs and try to do a cold install and debug it. When I started this, all my PCs already had plantuml dependencies installed so that never crossed my mind.

Oh man, just hit this same issue today again!

Installing graphviz with npm also has no effect.
I just can't install c4builder by any means.
