Visualization is the way of intelligently translating the invisible into a visible form. In the sphere of visibility, something new can appear visually to the eye and something new can appear intellectually to the mind. At the same time, visual languages are ambiguous and call for interpretation. In contemporary knowledge systems visualization plays an increasingly important role, contributing to a deeper understanding and to the transfer of knowledge. Digital technologies support traditional visualization techniques, and furthermore create new ways of analyzing and presenting information, allowing users to understand and handle huge amounts of information that are otherwise inaccessible. In addition visualization is considered as a way of effective interaction in civil projects and collective decision-making. Technologies expand the possibilities of visualization as a tool for thinking and communication in the context of increasing information complexity in science and society.
