Multi-resolution visualisation of geographic network traffic

Abstract

Flow visualization techniques are vastly used to visualize scientific data among many fields including meteorology, computational fluid dynamics, medical visualization and aerodynamics. In this paper, we employ flow visualization techniques in conjunction with conventional network visualization methods to represent geographic network traffic data. The proposed visualization system integrates two visualization techniques, flow visualization and node-link diagram. While flow visualization emphasizes on general trends, node-link diagram visualization concentrates on the detailed analysis of the data. A usability study with multiple experiments is performed to evaluate the success of our approach.
