Abstract : This doctoral research is focused on the visualization and interaction with multidimensional and temporal data. We tackle the challenges of: 1) designing visualizations for different users' expertise and needs; and 2) refining existing visualizations to enhance their usability and genericness or make them best-suited to a specific domain, need, and user. In this research overview we state the research problem and our plan of research. We then describe the achieved projects, each introduced with its closest related works. Finally, we present our future work perspectives.
