Abstract

Without doubt, we are in the midst of a data explosion. A variety of data 
tracking human mobility, namely human mobility data, has been generated and 
collected within urban context, providing unprecedented opportunities to 
understand regional dynamics in urban area, which is of great social and 
business value in a variety of applications. However, due to large volumes and 
dynamic correlations of these data as well as high complexity of analytical 
tasks in real world applications, it is challenging for analysts to carry out 
in-depth analysis and extract valuable information. It often requires 
integrating human perception in the data exploration process, triggering a 
broad use of visual analytics. With visual analytics, we can include human 
perception in the data exploration process efficiently and combine the 
flexibility, creativity and domain knowledge of human beings with enormous 
storage capacity and computational power of today
