Guest editors' introduction

Visual information communication and interaction generally encompasses information visualization, graphical user-interfaces, visual analytics, and visual languages. It has been successfully employed in knowledge discovery, end-user programming, modeling, rapid systems prototyping, education, and design activities by people of many disciplines including architects, artists, children, engineers, and scientists. In addition, visual information is increasingly being used to facilitate human-human communication through the Internet and Web technology, and electronic mobile devices.
