flowchart, n.: The innumerate misleading the illiterate.

— Stan Kelly-Bootle, “The Devil’s DP Dictionary”

A mechanical engineer who sees the symbol ⊥ in a diagram will immediately realize that a feature is specified to be perpendicular to another. In contrast, a software engineer looking at a diagram’s line ending with the symbol ◊ will, at best, wonder whether it denotes aggregation (as in UML), or a “zero or one” cardinality (as in IDEF1X), or something else invented by a creative academic.

In addition, I received a number of interesting patches and contributions. As a result I decided it was time to release UMLGraph version 5.1.

UML Class Diagrams from C++ Code

I needed a UML class diagram of the classes I use in the implementation of CScout refactoring browser. I drew the last such diagram on paper about four years ago, so it was definitely out of date. I always say that whenever possible documentation should be automatically generated from the code, so I decided to automate the task.
