The Gliffy Diagrams application can be installed on your Chrome for free. It allows you to draw various types of diagrams, such as basic UML and flow charts. I chose to use it in my introduction to programming course.
The tools itself is fairly basic and misses the finish we would have expected from a professional diagrams tool. In addition, it doesn’t support the relatively new UML 2.x diagrams. On the other hand its user interface is very simple and comfortable.
The simplicity of this tool and the easy installation on Chrome are the two reasons for my decision to use this tool when teaching basic introductory topics in programming. Using this tool we can easly create the flow chart diagrams.
