WiseMapping
WiseMapping is a free mind mapping web based application written in Java, SVG and HTML5. WiseMapping is licensed under the WiseMapping Public License Version 1.0. It provides extensive export capabilities and a user friendly drag and drop mind map editor.
As with other mind mapping software packages, WiseMapping allows the user to edit a hierarchical set of ideas around a central concept. The non-linear approach assists in brainstorming new outlines and projects as ideas are added around the mind map.
WiseMapping was invited to participate as part of WiseMapping SVG Open 2011 conference as example of how SVG can be used to design interactive applications.
