The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics, image processing, and visualization used by thousands of researchers and developers around the world.
Developed by the Lawrence Livermore National Laboratory, VisIt contains a rich set of visualization methods—such as contour plots, pseudocolor plots, volume plots, vector plots, and boundary plots—for visualizing scientific data. VisIt allows the ability to provide quantitative as well as qualitative information from a scientific data set.
DataDepot is a set of tools for collaboratively uploading, sharing, and analyzing data. You can use DataDepot to track personal data, to explore public data, and to engage with scientific data.
here's a lot of great information out there about politics — votes, lobbying records, campaign finance reports. Unfortunately, it's split across a dozen different web sites and often hidden behind confusing interfaces. We're pulling all of that together and letting you explore it in one elegant, unified interface. (Plus, we're sharing all the results so you can come up with new ways to explore it.)
Processing is an open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production. It is created to teach fundamentals of computer programming within a visual context and to serve as a software sketchbook and professional production tool. Processing is an alternative to proprietary software tools in the same domain. Processing is free to download and available for GNU/Linux, Mac OS X, and Windows.
