These days I've been noticing how important is to know how to create a good diagram to convey an idea. Also, working in a big company I noticed that we use UML diagrams for a lot of things, which is very useful to understand the architecture of the system or the design of the code. Does anyone here know some book or article that can help me to learn how to better convey ideas using diagrams, how to make one, and what diagram to use? I am not thinking about something very specific to UML, because I see that sometimes we just do a diagram that makes sense without following any standard.
