Sierra: A bipartite graph visualization

Bipartite graphs visualization shows different characteristics to general graphs visualization. The data model structure associated with bipartite graphs suggests a spatial distribution consists of two groups of elements separated physically but linked by relations. This article presents a quick review of some of the most common methods of bipartite graphs visualization and shows some simple alternatives to implement these methods. In addition, a new method for bipartite graphs visualization, called Sierra, is proposed. This method allows a quick and simple determination of the degree (number of links) of each node in the graph. Also, the method facilitates the identification of grouping between elements as the relationships that could exist between independent groups.
