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.
In this article, I will tell you about some really good alternatives of Microsoft Visio. But first let's try to understand why we need a replacement for Microsoft Visio? Well, the simple answer is that no version of Visio is available for less than US $300. If your budget is not matching this figure, you would certainly want to have a cheaper but powerful enough diagramming solution. I will begin with some handy free diagram and drawing software tools. These tools will come handy if you quickly need to put a diagram together for your project.
This free online facility is pretty straightforward. Go to the Draw.io website, select where you would want to store your diagram and just start drawing! No nonsense! Draw.io website offers you all the simple flowchart shapes, arrows, entity-relation shapes, UML diagram shapes, clipart and a lot of more stuff. You can even create your own customized shape by editing XML of an existing shape.
Draw.io can upload your diagram in Dropbox or Google Drive. You can also download the diagram in your computer. You can export the drawing as PDF, image, Scalable Vector Graphic (SVG) or XML. I often use this tool whenever I quickly need a basic diagram of any kind.

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.
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.

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.
Features and interface of LibreOffice Draw are same as that of OpenOffice Draw.
