• Draw is very similar to Visio. It's basically the free and open source version of it. You can create flowcharts with it like you can in Visio, and other things you can't do with Visio. Although Visio is more focused at creating flowcharts & diagrams and does very well at it, it's extremely expensive while Draw is free and open source. Guest • Aug 2018 Disagree   Agree
• It is hard to tell you that when I haven't started using it yet, but it appears to have the functionality I require without the expensive price, for sure. Guest • Sep 2018 Disagree   Agree
