Mindmap Wikipedia Content
WikiMindMap is a tool to browse easily and efficiently in Wiki content, inspired by the mindmap technique. Wiki pages in large public wiki's, such as wikipedia, have become rich and complex documents. Thus, it is not always straight forward to find the information you are really looking for. This tool aims to support users to get a good structured and easy understandable overview of the topic you are looking for.

This website appears to be a user friendly tool that would enable teachers (or anyone) to professionally produce diagrams, charts, graphs, and pictures. In my career, this would be a helpful tool for use in the classroom for both student interaction and setting up classroom rules and objectives.
