Finally, it´s also very easy to make logos and other types of graphics with the help of the ready-forms as well as the free-form option that you can use whenever you want. An additional thing I like is that the Dia Diagram is free and open spource. **What do you dislike about Dia diagram editor?** The only thing I can say I dislike is that, inside Dia Diagram´s panel, there are limited options when it comes to the pre-made forms that are available for instant use inside the software´s panel, I really wish there were many more forms to add.

But if you need more than this (such as complex illustrations) then aim to get Adobe Illustrator. **What problems is Dia diagram editor solving and how is that benefiting you?** There are a couple benefits I get from Dia Diagram: the first is that I can keep track of the limited processes I have inside my independent business, so that I can refer to them once and again in order to make my tasks easier and more standarized.
