Plotting the Afghan war, via Open Source Tools Turn WikiLeaks Into Illustrated Afghan Meltdown Updated | Danger Room | Wired.com:

It’s one thing to read about individual Taliban attacks in WikiLeaks’ trove of war logs. It’s something quite different to see the bombings and the shootings mount, and watch the insurgency metastasize.

Even more Afghan visualizations thanks to WikiLeaks are available  at Visualizing Data.

Endless possibilities

How many different user interfaces can you create for something completely banal? Read 1,000 Screens, 1,000 Dreams over on World Famous Design Junkies to see how something as simple and commonplace as scorekeeping for bowling can be complexified endlessly. Dozens of screenshots show the variations that can occur when you need to record a few columns and rows of numbers. What if this data was more complex?

Posts like this make me think that we’re only scratching the surface for Big Data visualization. How many ways can you envision a social network such as a series of cell phone calls? How soon before we transcend the boring lines-and-icons approach?

YouTube – Gource – Software Version Control Visualization Tool

Gource – Software Version Control Visualization Tool.

In Gource, software projects are visualized as they break out different branches, and split into different subprojects. Active users fly around zapping each node, representing software updates. The whole visualized node-and-line structure swirls, bends, and bounces like a rubber band.

The best thing about Gourse is the kinetic detail to the visualization, making each structure look like a tree wafting in a breeze.

All about the Benjamins: The Growth of Walmart

This visualization only looks like the spreading of a horrible plague. It is instead of the growth of Walmart and Sam’s Clubs throughout the United States. Starting in the relatively quiet 1960’s, Walmart added one or two locations a year. The flow accelerates until in 2010 there are 4393 stores studded across an apocalyptic consumerist landscape.

Density Mapping in Google Maps

Google API add-on lets you make heat maps inside a Google Map portal!

HeatMapAPI can be used over the Internet or as a .NET DLL that runs in a local environment and allows you to integrate heat map images into Google Maps or other GIS systems.  In this post we’re going to use HeatMapAPI to visualize the density of recent Starbucks store closures.  In a recent statement, Starbucks announced the closure of 600+ stores in the United States due to economic conditions.

In other news, we’d like to thank Starbucks for providing their easily-parsed list of closures. Most visualizations I’ve seen are using this dataset.

Introducing News Dots – By Chris Wilson – Slate Magazine

From Slate: News Dots. This little Flash-driven app renders the day’s events as a social network.

Like Kevin Bacon’s co-stars, topics in the news are all connected by degrees of separation. To examine how every story fits together, News Dots visualizes the most recent topics in the news as a giant social network. Subjects—represented by the circles below—are connected to one another if they appear together in at least two stories, and the size of the dot is proportional to the total number of times the subject is mentioned.

Graceful Timelines

We’ve all seen the unreadable timelines created by some analysis software. The hard lines, the veering connections. The mis-sized and aliased fonts. These might be sufficient for experts, but in the fullness of time, other more polished options will arise. Now you can make those veering connections into swooping connections.

The cartoon site XKCD.com did a few timelines for very complicated movie plots (Lord of the Rings, Star Wars trilogy, etc), modeling them after the famous “Napoleon’s Russian Campaign” chart. Sample:

Napoleon in Middle Earth

Anybody who has tried to write a mega-selling spy novel knows that the hardest part about plotting is getting all the interactions and conflicts on one page. Now we have a super online tool to help us do just that.

Introducing cs448b Data Visualizationhttps://graphics.stanford.edu/wikis/cs448b-09-fall/FP-OgievetskyVadim.

See the project description. Here is a sample poster.

The interface for the online tool (which is available here):

Plotting out the latest Mossad exploit? Wanting to show hookups in a crime family? This might be the tool for you. Project creator Vadim Ogievetsky says,

My main goal is to implement an efficient and effective layout algorithm that, with the users help, would generate results similar to the hand crafted images shown above. The layout algorithm will use combinations of genetic algorithms and simulated annealing to achieve the goal.
