Abstract

We present MeLVin-MEta Language for VIsualization, a meta-declarative language and a graphical framework to design interactive and coordinated view applications for visualization. Our framework is an abstraction layer placed over existing visual grammars and visualization declarative languages, providing them with interoperability mechanisms. The main contribution of this research is to provide a user-friendly system to design visualization and processing cards and connect them to form data analysis workflows. Cards and workflows can be saved, distributed and reused amongst users. We describe the characteristics of the framework, as well as two representative case studies to illustrate its capabilities. We also compare MeLVin with previous related works, discussing its advantages and disadvantages with respect to other frameworks.
