I love that it is a free tool. And you can also use it with other programs. The best thing about this program is that you do not need any prior experience in diagramming programs and you can easily understand how to use them by yourself. There are some tutorials that help to learn how to use it properly. This program has helped me in my professional work, since we have been using it to create diagrams for our projects. The ease of use, the graphic library is very good and extensive. I think it has some bugs that make it difficult to make changes or adjustments. For example, when using the "move" command, there are sometimes problems with the lines. It would be great if this was fixed. I recommend it because it's free and easy to use. I am solving several problems at once, which makes it perfect for my needs. I'm helping to create diagrams in order to teach people how to solve problems related to programming.
