While model-driven engineering (MDE) methodology has made significant improvements in terms of efficiency and effectiveness in many areas of software development, the same cannot be said of the development of data visualization systems. With this challenge in mind, this paper introduces DVDL (data visualization description language), a modular and hierarchical visualization description language that take advantage of the model-based design of MDE to describe visualization development at an abstract level. The paper also presents DVIZ (data visualization), a visualization system based on DVDL. With a growing popularity and demand for data visualization technology, a number of visualization tools have emerged in recent years, though few of them can be considered as adaptable and scalable as DVIZ. Key features in DVIZ include data source selection by user, property configuration of visual elements, and result publishing and sharing. The system also supports real-time result generation and multi-visual interaction. Lastly, since DVIZ is web-based, it supports result distribution across various social media.
