Recently I came across these diagrams, even though I learned about it long back! In this post I present you free tools to create flow charts, data flow diagrams and other architectural diagrams. I have included both the free desktop and web versions. I have also included trial version based software. Flow Diagram or flow chart is a diagram of the sequence of operations in a computer program or an accounting system. If you are unaware about DFD symbols, you can check this.
P.S. 1 If your diagrams are simple you can handle them using MS Word or other MS Office tools.
P.S. 2 The tools mentioned here are free to use, and for some you need to pay to enjoy full features, but still you can work on it.
