2. Algorithms

Each graph can be modified with algorithms for the layout, the set of selected objects, the size of nodes, the value attributed to an object (node or edge) named metric, the colors. An other advantage of Tulip platform is that it is easy to insert a new algorithm to the structure; this way, it is able to include lots of algorithm. As explain in the Section 1, “Main window : Menus”, the algorithms are accessed by the Property menu. Several categories are in there : Selection, Layout, Metric, Colors, Sizes. They modify the properties of the object in the graph.
