TreeCloud standalone application was originally developped by Philippe Gambette (). It was converted into GramLab plugin in order to build treecloud right in the GramLab. TreeCloud uses algorithm created by Philippe Gambette to compute distances between the words. NeighborJoining algorithm (Saitou, Nei 1987) for computing the tree from distances and EqualAngle algorithm for building the tree. The tree is renderred in SVG format using Apache Batik SVG Toolkit. You can export the tree into several formats: Newick, SVG, PDF, JPEG. For more information please refer to the TreeCloud manual ().
The SVG picture is not dynamic, that is, there is not yet possibility to zoom or rotate the picture. Moreover, there is no possibility to drag the words in case they are overlapping each other. These functionalities will be added in the next version. Stopwords can be removed only from trees built on English, French, Spanish, Portuguese and German languages.
You can improve the plugin by reporting about the bugs or posting the issues here.
