Need to create a simple diagram of a piece of software? Try the Umbrello tool located under the applications menu. It allows you the design and structure of programs in a standard format. To find Umbrello look under Applications and then Programming. Umbrello will be at the bottom (the lists are in alphabetical order). If you are in the middle of creating a diagram and get stuck, you can ask for help from their community located Here. Hopefully Umbrello makes it a little bit easier for you to create cool things here at the library, and happy diagraming!
