Analytical Visualization Framework

Example Visualization of poverty statistics for districts in Ghana constructed from transformation modules using the Analytical Visualization Framework. Colored map, table view and value distribution histogram provide different perspectives on the same data
A visual approach to mining, processing and access of multi-disciplinary data

The Analytical Visualization Framework is an open source tool for visualization and interactive data manipulation with special capabilities to handle geographic information.

It is a cross-platform Java-based application, that can be integrated in the daily work of analysts and researchers. Its data transformation capabilities can be used in server-side computations providing the basis for feature-rich web services.

The framework allows users to analyze and visualize scientific data without the need to install expensive commercial software.

Benefits of the framework

  • Multiple views, multiple perspectives – several coordinated visualizations constructed from the same data display different data characteristics for better understanding of the overall situation
  • Interactive data manipulation – all changes in computation designs are visualized immediately. Only the parts that depend on the change are recomputed providing fast response that improves productivity
  • Modular architecture – complex computations are constructed from general purpose modules
  • Reusable components – structures composed from other modules act as higher-level modules that can be used in other structures or applied to other data
  • Rich palette of library modules – the framework comes with modules for generic computations as well as special modules for manipulation and visualization of geographic information in vector and raster formats
  • Programmer's API – open libraries, module templates and examples allow advanced users with Java programming skills to develop their own modules according to their needs
  • The main workspace of the Analytical Visualization Framework. The modules can be dragged and dropped from the library (upper left frame). Links between modules can be interactively assigned in graph editor or in the module inspector panel (bottom left).
