Before submitting a new icon request, please confirm the following:

• [X] I have searched all issues to make sure there isn't a request for this icon.
• [X] I have searched the current library to make sure the icon doesn't already exist.

• [X] I only intend to request a single icon (or a few near-identical ones) in this issue.

What would you use this icon for?

I have an application that generates some uml diagrams for user. And I want to add icon to item menu for this functionality. Currently MaterialDesign contains only chart icons but there is no diagram icons at all.

Give us an example of what this icon might look like.
