摘要：Interactions become essential in Visualization because they enable users to adapt the visual representation to their own needs allowing them to explore the underlying information space. By using non-conventional devices, they face a wider fan of interaction possibilities to explore their data. But, there is still not an agreed base theory to describe the processes involved in the visualization pipeline data transformation and, from the interaction viewpoint, it does not exist an interaction classification that allows presenting them under a unified perspective. The objective this work is to contribute to develop a Graph Visualization base classifying and defining the most representative interactions in the field. On this basis, it will be intended to lay the foundations to obtain a systematic development of interactive visualization tools using non-conventional devices. Then, an interaction over graphs' taxonomy is proposed, all their categories are placed in the reference model context and the most relevant aspects to design visualizations using this kind of devices, are analyzed
