Converting scanned graphs to data. Converting scanned graphs to data, that is, extracting (x,y) data from scanned graphs can be useful for analyzing data from published graphs, analog instruments, strip chart recordings, or any other hard copy graph or plot. This is sometimes called a "plot digitizer", "graph digitizer", or "optical plot reading" (OPR).[1] History[edit] Developments of the 20th century computer were fueled largely by the needs of the scientific community to store and analyze large amounts of scientific data.
With the later development of the personal computer and graphics printer, scientists were able to easily display and print graphical representations of their data sets. Although digital video systems and scanners were developed primarily to input and manipulate pixel images such as pictures, drawings and photographs,[2] it soon became clear that information could be extracted from other types of scanned images.

Welcome to the DARPA Open Catalog, which contains a curated list of DARPA-sponsored software and peer-reviewed publications.
DARPA sponsors fundamental and applied research in a variety of areas including data science, cyber, anomaly detection, etc., which may lead to experimental results and reusable technology designed to benefit multiple government domains. The DARPA Open Catalog organizes publicly releasable material from DARPA programs.
DARPA has an open strategy to help increase the impact of government investments. DARPA is interested in building communities around government-funded software and research. The table on this page lists the programs currently participating in the catalog. Program Manager: Dr. Report a problem: opencatalog@darpa.mil. 5 books on data visualization.

The top 20 data visualisation tools. 22 free tools for data visualization and analysis. You may not think you've got much in common with an investigative journalist or an academic medical researcher. 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.
If one of the higher-priced options is out of your reach, there are a surprising number of highly robust tools for data visualization and analysis that are available at no charge.

A visual exploration on mapping complex networks. Fidg't: Your Social Networking Address Book. Explore your network with the Fidg't Visualizer* The Fidg't Visualizer allows you to play around with your network.
You interface with the Visualizer through Flickr and LastFM tags, using any tag to create a Magnet. Once a Tag Magnet is created, members of the network will gravitate towards it if they have photos or music with that same Tag. This simple mechanic lets you visualize your Network in a unique way, demonstrating its Predisposition towards certain things. What is more popular amongst people in your Network - rock or electronic music? For good measure, you can also search through the network for certain users, and check out their recent photos and music. The Fidg't Visualizer is in an alpha release. Windows users might need to download Java, which can be done here . *You can download and play with the Fidg't Visualizer even if you haven't created a Fidg't account. 8.1.07 Thanks to Casey Reas for putting our Visualizer up on the Processing Home Page.

McKinsey Web 2.0 Visualization. For the past seven years, thousands of executives from around the world—across a range of industries and functional areas—have responded to a McKinsey survey on how organizations are using social (or Web 2.0) technologies. In 2009 we created an interactive tool that links the data from these survey results and charts it to the emerging trends in Web 2.0 adoption. This interactive focuses on several of the survey’s core questions—from what technologies and tools companies view as most important to what kind of investments, if any, organizations plan to make in Web 2.0 in the future.
Our most recent survey examines the business use of 13 social technologies and tools: blogs, collaborative document editing, mash-ups (a Web application that combines multiple sources of data into a single tool), microblogging, online videoconferencing, podcasts, prediction markets, rating, RSS (Really Simple Syndication), social networking, tagging, video sharing, and wikis. Interactive. Roambi. Protovis. Protovis composes custom views of data with simple marks such as bars and dots. 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). The Protovis team is now developing a new visualization library, D3.js, with improved support for animation and interaction. This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates May 28, 2010 - ZOMG! Getting Started. Many Eyes.
