Big data visualization technology and applications

With the growth of data generated by human activities, the scale, the type and the demands for the data visualization have expanded greatly. In the big data era, the data visualization faces many challenges. In this paper, based on the characteristics and the requirements of the big data, and the current research states of the data visualization, the common data visualization techniques are reviewed. Eight important challenges that the data visualization has to deal with in the big data applications are highlighted. The AutoVis, a data-aware interactive visualization design platform, is specially discussed, as well as its applications.
