Visual Physics Analysis
VISPA is a novel development environment for high energy physics analyses, based on a combination of graphical and textual steering.
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, 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), which is a successor project of the Physics Analysis eXpert (PAX) package. The most prominent features of this toolkit are the management of relations, a copyable container holding different aspects of physics events, the ability to store arbitrary user data, and a fast I/O.
