It is always easier to plan and remember information that is represented as a diagram. Most of you must have used diagrams like flow charts, mock charts, maps, floor layouts, work flow charts and network plans etc. All these are the diagrammatic representation of data and processes that we develop in our mind. In olden days, these diagrams used to be created on paper. But now, in the digital age, we have computer software that enable us to swiftly create neat diagrams. Microsoft Visio is the leading diagramming software. There is no doubt about the power of Visio but this capability comes at a big price. An hefty price tag makes Visio suitable only for big businesses. Small teams and individual users often look for free diagramming software or for software that are less expensive.

OpenOffice Draw

Just like Microsoft Office contains Visio, OpenOffice contains a software called Draw. Both have similar features but, as you know, OfficeOffice comes for free because it is an open source software. OpenOffice is the biggest competitor of Microsoft Office. Therefore it is not surprising that OpenOffice Draw is packed with features that will help you in creating amazing drawings and diagrams. You can create as large as 300cm X 300cm posters. You can even create Flash (.swf) files using Draw.

With OpenOffice Draw you can create sketches, layouts, diagrams and drawings.

What’s more? OpenOffice Draw doesn’t bind you to itself. You can not open a Visio file in any other software, but if you save your diagram as an OpenOffice document —which is a standard in industry —you can easily use other software to open and edit the file create by OpenOffice. The only condition is that the software should be compliant with the OpenOffice standard.

LibreOffice Draw

For those who don’t know, LibreOffice and OpenOffice are two branches of the same code base. As a result, both these software are quite similar to each other. OpenOffice is being developed by the Apache Foundation whereas LibreOffice is being developed by The Document Foundation. LibreOffice has been advancing at a better pace than OpenOffice. If you ask me, choosing LibreOffice is a better idea.

    Hello Lalit! A nice guide:) thanks. I wondering is there still any free diagramming tools that can open and edit both vsdx and vsd files? (indeed it’s hard to find a free one with good features now).

    I’m using Visio 2016 pro and sometimes I need to switch between different tools for my work. I found Edraw Max can do that, but I need to pay the full version for making any changes to my Visio files (only open and view are free). Lucidchart is also not free to edit visio files.

  2. John says:

    Lalit, I’ve tried several of the tools you mentioned. OK, but pretty rough around the edges.

    Work recently adopted Lucidchart as a Visio replacement. It has imported my Visio files quite well and the real-time collaboration has been a nice perk.
