Visualization, transforming data into pictures for storytelling or discovery, as a discipline has quickly grown its importance in data-driven scientific studies, engineering designs, and business operations. Over the past decade, visualization as a field of study as well as problem-solving tool has received considerable attention in the U.S., Europe, Japan, South Korea, and China. Tremendous research investments have been made by their government and industry. However, in Taiwan, visualization has received little attention except in a small number of application areas. The potential impact of visualization on a wide range of data-driven problem solving and decision making tasks seems to be largely neglected. This workshop aims to bring together visualization researchers, practitioners, and users of visualization in Taiwan and initiate a dialogue between them. Together, the workshop attendees will learn about existing visualization research and development activities, challenging data visualization and analytics problems, emerging application areas, research opportunities, prospective users and collaborators, etc. The workshop will be composed of invited talks and a panel discussion.
