It is recognized as an essential tool by modern business since it is able to convert data into business intelligence thus giving an informational edge. At present, it is widely used in profiling practices, like surveillance, marketing, scientific discovery, and fraud detection. Processing.org. d3.js. DataWrapper, a project by DataStory.

Improvise. Exploratory visualization based on multiple coordinated views is a rapidly growing area of information visualization.

Improvise

Ideally, users would be able to explore their data by switching freely between building and browsing in a flexible, integrated, interactive graphical environment that requires little or no programming skill to use. However, the possibilities for displaying data across multiple views depends on the flexibility of coordination, the expressiveness of graphical encoding, and the ability of users to comprehend the structure of their visualizations as they work. As a result, exploration has been limited in practice to a small fraction of useful visualizations. Extractiv. GraphStream - A Dynamic Graph Library. Colorbrewer: Color Advice for Maps.

But if you're trying to extract useful information from an ever-increasing inflow of data, you'll likely find visualization useful -- whether it's to show patterns or trends with graphics instead of mountains of text, or to try to explain complex issues to a nontechnical audience. There are many tools around to help turn data into graphics, but they can carry hefty price tags. The cost can make sense for professionals whose primary job is to find meaning in mountains of information, but you might not be able to justify such an expense if you or your users only need a graphics application from time to time, or if your budget for new tools is somewhat limited.

ImagePlot visualization software: explore patterns in large image collections

ImagePlot is a free software tool that visualizes collections of images and video of any size. It is implemented as a macro which works with the open source image processing program ImageJ. ImagePlot was developed by the Software Studies Initiative with support from the National Endowment for Humanities (NEH), the California Institute for Telecommunications and Information Technology (Calit2), and the Center for Research in Computing and the Arts (CRCA).

Our visualization will provide an animated force-directed layout of a social network, with nodes colored according to gender and showing the names of people they represent. All code presented below is assumed to be within the main method of an application class. The full code for this example is available as Example.java. Example Application: A Simple Social Network Visualization 1. loading data The first step is to load the graph data into a prefuse Graph instance. Graph graph = null; try { graph = new GraphMLReader().readGraph("/socialnet.xml"); } catch ( DataIOException e ) { e.printStackTrace(); System.err.println("Error loading graph. If you are having trouble loading the file, either make sure the prefuse data directory is on your classpath, or, alternatively, change the file location.

IMPURE. Application. Protovis. Protovis composes custom views of data with simple marks such as bars and dots.

Protovis

Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates. Data Wrangler.

Software Cartography. — “It is our vision that developers can speak of code as ‘up in the north’, ‘over in the west’, or ‘down-under in south’. We want to provide developers, and everyone else involved in software development, with a shared and spatial and stable mental model of their project.

They way we try to reinforce this, is by providing a map in the Integrated Development Environment (IDE). The map is always visible in the bottom-left, just like the GPS navigation device in your car. Treevis.net. Beautiful Word Clouds. Public Data Explorer.
