VISPA New York Summary
2012-12-17, A Server-Client-Based Graphical Development Environment for Physics Analyses (VISPA), Proc. CHEP 2012 NY, USA, 2012 J. Phys.: Conf. Ser. 396 052015
Visual Physics Analysis
VISPA provides a development environment for physics data analysis with special emphasis on high energy physics, and astroparticle physics. It is based on a combination of graphical and textual steering. VISPA is available as a desktop version, or can directly be accessed through your web browser:

Brief tutorial on how to access the web system & run an example analysis.
A more advanced introduction of using the VISPA web service can be found here.
Install the desktop version of VISPA from here.
For advanced users wishing to setup their own server-client system download the VISPA web-system here.
The primary aim of VISPA is to support physicists in prototyping, performing, and verifying a data analysis of any complexity. The combination of graphical and textual steering has been shown to speed up design and development in other fields, e.g. hardware control using the LabView program.
To deploy a visual environment for physics analysis, the desktop version of VISPA provides a multi-purpose window tool with a three-column structure - a navigator panel, a window for graphical displays, and a property panel. For the text-based programming, both the C++ and the Python languages are supported. VISPA heavily uses the Physics eXtension Library (PXL). The most prominent features of this toolkit are the ability to store arbitrary user data, management of relations, a copyable container holding different aspects of physics events, and a fast I/O.
