A radial tree, which is also known as a radial map is a method of studying the structure of trees, and find out all the data there is to offer. The method is such that in the map, the structure of the tree in question radiates outwards, or expands outwards, which makes it easier for scientists to study its intricacies.
The Radial Tree Viewer is a tool which was developed by Nihar Sheth, at the School of Informatics, in the Indiana University. The Radial Tree Viewer is an extended version of the original Radial Tree Browser, which in turn was built by Jason Baumgartner along with Nihar Sheth. It forms the most integral aspect of the Information Visualization Software Repository, which also goes by the name IV Repository.
The Radial Tree Viewer can be used and its functions implemented to conduct many scientific studies, including the support of the interactive comparison between two trees, which are phylogenetic, for studies which help display the structure of hierarchy belonging to a large hierarchy of classification, and for tasks which help to study the differences between various directory logs. The Radial Tree Viewer, hence, is a very important tool when it comes to the study of trees.
