There's been times in the past when I've had nontechnical stakeholders present for otherwise technical meetings. A little bit of colour and a little bit of animation can go a long way to helping people who may be less familiar with this type of diagram to understand it better.

All the better if I can take an existing diagram and just spruce it up slightly for presentation.

I’ve done my fair share of diagramming and one thing I know for sure is markup (In he visual one) needs to be as clear as possible.

As someone who started with demo scene and all I can understand the drive to have moving parts and all the gay stuff, but many people get easily confused by colours and animation.
