Ten Simple Rules for Better Figures

Ten Simple Rules for Better Figures | Data visualization | Scoop.it

Scientific visualization is classically defined as the process of graphically displaying scientific data. However, this process is far from direct or automatic. There are so many different ways to represent the same data: scatter plots, linear plots, bar plots, and pie charts, to name just a few. Furthermore, the same data, using the same type of plot, may be perceived very differently depending on who is looking at the figure. A more accurate definition for scientific visualization would be a graphical interface between people and data. In this short article, we do not pretend to explain everything about this interface; rather, see [1], [2] for introductory work. Instead we aim to provide a basic set of rules to improve figure design and to explain some of the common pitfalls.

A Striking New Way to Visualize Mobility

A Striking New Way to Visualize Mobility | Data visualization | Scoop.it
This tool shows how far you can travel in 10 minutes in ghostly splotches and tendrils.

For quick info on routes and travel times, there's always Google Maps. But for a traveler wanting more of a beauteous, immersive experience, try Isoscope, a mapping tool that plots possible journeys in what looks like glowing-blue ectoplasm.

Isoscope is not a service one would use to get from point A to B. It's more of a way to explore mobility in areas where travel conditions change hour by hour. First, set the map to zoom in on any place in the world and click it to site your imaginary traveler. A ghostly, translucent presence will then form, all splotches and tendrils. This cerulean shape is actually 24 different layers representing all the hours of the day. Track the mouse over the hours at the map's bottom, and the shape's outline will expand and contract to show how far you can get in a preselected two-to-ten minute car trip.

Arctic Sea Ice Takes a Hit From Warm Rivers

Arctic Sea Ice Takes a Hit From Warm Rivers | Data visualization | Scoop.it

Suspecting there might be a relationship between seasonal river outflows and the region’s shrinking frozen skin, a team of scientists from NASA’s Jet Propulsion Laboratory took a close look at the Mackenzie River delta in western Canada, which runs from a point near Yellowknife to the Beaufort Sea. In 1998, Beaufort Sea ice coverage was the lowest on record — and outflows from the Mackenzie River system were the largest on record. But it was 2012 when sea ice coverage was the lowest throughout the Arctic. In the early summer of that year, the Mackenzie river was kept at bay behind an icy dam. It broke through the dam sometime between June 14 and July 5, flooding the sea with water that had been collecting behind the barrier.

Over-Medicated America

Over-Medicated America | Data visualization | Scoop.it

1 in 2 Americans are taking prescription drugs right now.Though medication has helped countless people over years, drug companies, in their endless pursuit of profit, now push more medications than ever before, with the help of the FDA and unscrupulous doctors. But the vast majority of new drugs won't help you - and may even hurt you.

The Role of Algorithms in Data Visualization

The Role of Algorithms in Data Visualization | Data visualization | Scoop.it

It’s somewhat surprising to me to notice how little we discuss about the more technical side of data visualization. I use to say that visualization is something that “happens in your head” to emphasize the role of perception and cognition and to explain why it is so hard to evaluate visualization. Yet, visualization happens a lot in the computer also, and what happens there can be extremely fascinating too.

So, today I want to talk about algorithms in visualization. What’s the use of algorithms in visualization? When do we need them? Why do we need them? What are they for? Surprisingly, even in academic circles I noticed we tended to either avoid the question completely or to take the answer for granted. Heck, even the few books we have out there: how many of them teach the algorithmic side of visualization? None.

A Bewitching Look at Migration Patterns Among American States

A Bewitching Look at Migration Patterns Among American States | Data visualization | Scoop.it

New York residents must really get sick of the winter snow and gloom. How else to explain that more of them moved to Florida in 2012 than any other state?

That's just one of the fascinating nuggets of demographic trivia waiting to be uncovered in this wild-looking visualization of state-to-state migrations. The prismatic, arc-veined portal – like peering into the scope of an alien hyper-rifle – shows the movements of the roughly 7.1 million Americans who relocated across state lines in 2012. It's based on the U.S. Census Bureau's American Community Survey, an annual tabulation of moves that just so happens to include the involuntary uprootings of prisoners and members of the military.

Visualizing Algorithms

Visualizing Algorithms | Data visualization | Scoop.it

Algorithms are a fascinating use case for visualization. To visualize an algorithm, we don’t merely fit data to a chart; there is no primary dataset. Instead there are logical rules that describe behavior. This may be why algorithm visualizations are so unusual, as designers experiment with novel forms to better communicate. This is reason enough to study them.

But algorithms are also a reminder that visualization is more than a tool for finding patterns in data. Visualization leverages the human visual system to augment human intellect: we can use it to better understand these important abstract processes, and perhaps other things, too.

Inside the $400-million political network backed by the Kochs

Inside the $400-million political network backed by the Kochs | Data visualization | Scoop.it
In an analysis of 2011 and 2012 tax filings, The Washington Post and the Center for Responsive Politics found that a coalition of nonprofit groups backed by a donor network organized by the billionaire industrialists Charles and David Koch raised more than $400 million in the last election cycle. Much of the money was distributed to a maze of limited-liability companies affiliated with the nonprofits, which used some of their resources to turn out conservative voters and run ads against President Obama and congressional Democrats.
