With the incorporation of web 2.0 frameworks the complex- ity of decision making situations has exponentially increased, involving in many cases many experts, and a pontentially huge number of differ- ent alternatives. In the literature we can find a great deal of method- ologies to assist multi-person decision making. However these classical approaches are not prepared to deal with huge complexity environments such as the Web 2.0, and there is a lack of tools that support the deci- sion processes providing some graphical information. In this context is where data visualizations plays a key role. Therefore the main objective of this contribution is to present an open source tool developed in R to provide a quick insight of the evolution of the decision making by means of meaningful graphical representations. These tools allows its users to convey ideas effectively, providing insights into a rather sparse and com- plex data set by communicating its key-aspects in a more intuitive way and contributiong to the decision maker engangement in the process.
