The 4th IEEE Pacific Visualization Symposium (PacificVis 2011 or Pacific Vis 2011) will be held in Hong Kong during March 1 to 4, 2011. Hong Kong is a splendid mixture of tradition and modernity as well as a center of business in the world.

Visualization has become an increasingly important research area due to its wide range of applications in many disciplines. PacificVis is an IEEE sponsored international visualization symposium held in the Asia-Pacific region, with the objective to foster greater exchange between visualization researchers and practitioners, and to draw more researchers in the Asia-Pacific region to enter this rapidly growing area of research. The former name of PacificVis was APVIS (Asia-Pacific Symposium on Information Visualization). This new venue has an expanded scope to include all areas of visualization, and a sponsorship to allow us to achieve a more wide-spread impact.
