Bilbao 2015 15 •  Data visualization and visual analytics tools empowers users to understand and manage complex datasets, even if they have not (too much) previous experience using this kind of systems. •  Nowadays researchers have access to many analytics tools and visualizati on tools. It is responsibility of them to distinguish what of them are the mos t suitable for solving their research problems. •  The systems for Learning Analytics and Visual Analytics should not be considered only as tools, but like complete systems backed by formal mod els. •  VeLA demonstrates the enormous potential of the Visual Analytics applied to Learning Analytics, and leaves open a promising line of research
