The application of data visualization to exploratory analysis has proven its effectiveness in different scientific fields. Unfortunately, each discipline suffers from specific problems, making it difficult to apply general solutions. MeLVin is a graphical meta-framework for our MEta Language for Visualization. It was created to facilitate the design of interactive coordinated views applications for visual exploration of data using different technologies. The platform is conceived as an abstraction layer placed over existing data visualization and processing environments, enabling their integration. The data analysis workflow can be seamlessly defined using data-flow diagrams (DFD). Unlike most data-flow diagram-based data mining applications, MeLVin allows users to include visualizations as part of the analysis process and not just as a tool to display final results.

Melvin was designed to fulfill the following requirements:
