PROTOVIS-JAVA RESEARCH PROTOTYPE Protovis-Java is a partial implementation of the Protovis toolkit in the Java programming language. It is a research project exploring how Protovis' declarative approach to visualization design can be implemented and optimized in a statically-typed, object-oriented language. We demonstrate how to support rich visualizations without requiring a toolkit-specific data model and extend Protovis to enable declarative specification of animated transitions. To support cross-platform deployment, we introduce rendering and event-handling infrastructures decoupled from the runtime platform. For more information about the design of the system, see our InfoVis 2010 paper: http://vis.stanford.edu/papers/protovis-design This software package provides only a partial implementation of the full Protovis language and includes only selected subcomponents explored during our research. Please note that this is *only* a research prototype! It is not intended to be a production-ready toolkit and we do not provide software support as of this time. The code is also missing many of the library routines familiar to Protovis-Javascript users. For a complete, production-ready system, we encourage you to use the fully supported JavaScript implementation, available at http://protovis.org We provide the code here freely for others to use and modify, and as supporting material for our research paper and benchmarks. Protovis-Java is released as open source software under a BSD license. Please see the included protovis-license.txt file for the licensing terms. ----- The software consists of 3 sub-projects: protovis -> The Protovis-Java language implementation protovis-benchmarks -> Code for performance benchmarks in the research paper protovis-examples -> Example Protovis applications Each sub-project includes .classpath and .project files for use in Eclipse. The "build" directory contains pre-compiled jar files and dependencies, as well as scripts to launch the various examples. The "lib" folder includes platform-specific JOGL 1.1 libraries for Mac OS X. To run examples under Windows or Linux, you will need to download platform-specific binaries for those systems and place them in the folder.
