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). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates June 28, 2011 - Protovis is no longer under active development. September 17, 2010 - Release 3.3 is available on GitHub. May 28, 2010 - ZOMG! Getting Started
Gephi, an open source graph visualization and manipulation software APEXvj - Visualize your favourite tunes online Screensaver - visualizing the global blogosphere Twingly Screensaver Beta Twingly screensaver is visualizing the global blog activity in real time. Forget RSS readers where you see only what you're interested in. With Twingly screensaver you get a 24/7 stream of all (viewer discretion advised) blog activity, straight to your screen. To use the screensaver you need a PC with Windows and a graphics card supporting OpenGL. Enable Asian language support in Windows, there's lot of that stuff in the blogosphere. How to install: Download the installation files by clicking the download button. To use Twingly as the system screensaver: Right click the desktop.
blog » Hexbins! Binning is a general term for grouping a dataset of N values into less than N discrete groups. These groups/bins may be spatial, temporal, or otherwise attribute-based. In this post I’m only talking about spatial (long-lat) and 2-dimensional attribute-based (scatterplot) bins. Such binnings may be thought of as 2D histograms. This may make more or less sense after what lies beneath. If you’re just after that sweet honey that is my code, bear down on my Github repository for this project — hexbin-js. Rectangular binning The simplest 2D bin is rectangular. The above is a shot from a little example I produced on jsFiddle, while learning Mike Bostock’s fantastic D3 JavaScript library for HTML and SVG data-binding and visualization. Binning can be good for both the users and the creators/developers of static or interactive thematic maps or other visualizations. So anyway, binned representations can be beneficial for both users and creators. Hexagonal binning Adler writes, Hex history and theory
Web Trend Map 4 by Oliver Reichenstein The has been featured all across the web from TechCrunch to BoingBoing, and Gawker. Now the latest version of our popular Web Trend Map is up for grabs. Sold out – Sorry, the Web Trend Map 4 is no longer available. We grouped together closely associated websites, ensuring that every domain is on an appropriate line. The map has been printed by the same printer that prints Apple’s ads in Japan, so you can be sure its handled by the best. About Google+ Ripples - Google+ Help Google+ Ripples creates an interactive graphic of the public shares of any public post or URL on Google+ to show you how it has rippled through the network and help you discover new and interesting people to follow. Ripples shows you: People who have reshared the link will be displayed with their own circle. Inside the circle will be people who have reshared the link from that person (and so on). The comments users added when they reshared a link are displayed in the sidebar of Ripples. At the bottom of the Ripples page, you can play an animated version of the visualization that shows how the link was shared over time. Beneath the timeline on the Ripples page statistics on the link. While Ripples displays a lot of cool information, you’re not actually seeing all the action that’s taken place. To view Ripples for a public post in your stream, just click the dropdown arrow at the top of the post you’re curious about and click View Ripples. Not sure if a post is public?
Mapping the Internet The increased use of peer-to-peer communications could improve the overall capacity of the Internet and make it run much more smoothly. That’s the conclusion of a novel study mapping the structure of the Internet. It’s the first study to look at how the Internet is organized in terms of function, as well as how it’s connected, says Shai Carmi, a physicist who took part in the research at the Bar Ilan University, in Israel. While efforts have been made previously to plot the topological structure in terms of the connections between Internet nodes–computer networks or Internet Service Providers that act as relay stations for carrying information about the Net–none have taken into account the role that these connections play. The researchers’ results depict the Internet as consisting of a dense core of 80 or so critical nodes surrounded by an outer shell of 5,000 sparsely connected, isolated nodes that are very much dependent upon this core.
