5 Best Free/Open-Source Mind Mapping Software for Linux

An outline used to illustrate words, ideas, tasks, or other items linked to and arranged around a central key word or idea is called a mind map. A mind map is utilized to manage ideas and arguments making it an effective utility in study, organization, problem solving, decision making, and writing.

Since mind mapping techniques have been proven to enhance learning more efficiently than the conventional note taking, several mind mapping software have been created. Here are some of the best Free and Open Source mind mapping applications that are available for Linux:

FreeMind
FreeMind is probably one of the most if not the most popular mind mapping application for Linux. In 2008, it was nominated for Best Project category in SourceForge.net's Community Choice Awards. Free mind is written in Java making it portable across multiple platforms. As with other mind mapping software packages, it allows the user to edit a hierarchical set of ideas around a central concept. Here are some of FreeMind's most important features:

VUE (Visual Understanding Environment)
The Visual Understanding Environment (VUE) is developed by the Academic Technology group at Tufts University. It is focused on creating flexible tools for managing and integrating digital resources in support of teaching, learning and research. VUE provides a flexible visual environment for structuring, presenting, and sharing digital information. Using VUE's concept mapping interface, faculty and students design semantic networks of digital resources drawn from digital libraries, local and remote file systems.

XMind
XMind is a brainstorming and mind mapping software tool developed by XMind Ltd. It supports mind maps, fishbone diagrams, tree diagrams, org-charts, logic charts, and even spreadsheets.
