Daily mobility described by individual displacements performed over 24-hours periods provide the analysts with powerful information about the real rhythm of the cities, which can be applied for providing more appropriate transportation policies and investment decisions. The most recent researches in geovisualization have focused on the development of multiple coordinated views environments, which enable the combination of spatial (e.g., cartographic visualization) and temporal (e.g. timelines) dimensions, and the data comparison. Nevertheless, these environments describe either the activity projects at the individual level (e.g. Space-Time Cube) or the movement dynamics within a territory at the aggregated level according to a specific geographic scale (e.g. through flow maps). The analyze of daily mobility is highly complex and requires the simultaneous exploration and combination of different mobility indicators at different spatial and temporal granularity. Nonetheless, design an effective geovisualization environment to support daily mobility analysis is a challenging task, because of the diversity and multiplicity of indicators, the different granularity of space and time, and the time integration itself. In this paper, we propose an interactive geovisualization environment that enables dynamic visualization of different indicators through a set of visual representations, and explore them through different levels on space and time. Our approach supports the association of multiple flexible dashboards, which enables the user to rearrange views and compare indicators considering different aspects of the data. Further, we integrate a second screen which serves as display and interaction tool, enabling the user physically to explore the time dynamics of the data.
