The plugin adds a scripting panel where you can write python script to transform the network, compute metrics, apply layout etc.
Plugin Owner's Notes
The Script Console plugin provides a text input where user can insert and execute python code. This code can interact with the current graph and user can perform many operation on it. Most of the API of the Gephi Toolkit are accessible, but the plugin provides also some easier utility functions to hide some complexity of the gephi toolkit. Its goal is to add some of the functionnality of GUESS to gephi.
