Today’s post looks at an interactive graphic from the Los Angeles Times. The subject matter is piracy and the piece has three distinct views, the second of which is displayed here.
Pirate attacks in the Indian Ocean
Generally speaking, the package is put together fairly well. My biggest concern is with the first graphic. It uses circles to represent the number of attacks by locale over time. I would have either included a small table for each geographic area noted, or instead used a bar chart or line chart to show the progress over time.

Today’s piece comes from Bloomberg and looks at the cost of Chicago’s gun violence epidemic. And when I write cost, I mean just that. While the lives lost are the most significant, Bloomberg’s article states that shootings cost Chicago $2.5 billion per year, or $2,500 per household. They supplemented their article with an infographic detailing and breaking down these costs by focusing on the South Shore in the city’s south side.

Earlier this month the Federal Reserve Bank of New York published a report on household debt. Among the findings was the story that student debt is rising to problematic levels as it may act as a brake on economic recovery. In short, without an economy creating jobs for the young (recent university graduates) it becomes increasingly difficult for the young to pay pack the loans for the sharply rising costs of university tuition.
The report made this argument by use of interactive choropleth maps and charts. The one below looks at
Which consumers have how much debt
But another chart that talks about the rising levels of student loan debt misses the mark. Here we see some rather flat lines. Clearly student loans are growing, but without a common baseline, the variations in the other types of debt muddle that message.
The NY Fed's presentation of non-housing debt
I took the liberty of using the data provided by the New York Fed and charting the lines all separately. Here you can clearly see just how in less than ten years, student loans have risen from $200 billion to $1,000 billion. This as credit card debt is falling along with other forms of debt (non-automotive).
My take on non-housing debt
The New York Fed did some great work, but with just one tweak to their visualisation forms, their story is made much more powerful and much more clear.

Here’s an older, March graphic from the New York Times that looks at Alaska Airlines. This exemplifies what maps do well; it maps relevant data onto a map. Perhaps that reads silly, but too often people map data just because most things are tied to a geography; things that happen in the world happen somewhere, ergo everything could be mapped.
The growth of Alaska Airlines
In this graphic, however, mapping the tight and Alaska-focused network with tendrils sneaking off-map to distant cities. The map supports the article that tells how after decades of focusing on Alaska, the airline has begun to expand to Midwestern cities in the US, cities in Mexico, and Hawaii.
I am not terribly keen on the stacked bar chart. It highlights the steady Alaska market over the decades at the cost of showing dynamism in those Midwestern, Mexican, and Hawaiian markets.

Last year Hurricane Sandy wrecked swathes of the Jersey Shore and Long Island. Since then, authorities and officials have been busy preparing and rebuilding the shore for the unofficial start of summer: Memorial Day Weekend. This interactive map from the New York Times looks at what will be open for Memorial Day from Connecticut through Long Island to as far south as Margate.
What beaches will be open along the shore
Once you find your preferred beach, you can see the details of what will be open, closed, or otherwise different. This is the view for Atlantic City, nearest to the southern New Jersey shore towns where I spent so many years but are left off the map.

This choropleth map comes from Deadspin and it looks at each state’s highest paid public employee. As you can probably imagine since the graphic comes from Deadspin, most states pay their highest wages to sports coaches. Ten states pay somebody other than a sports coach. And five of those are in the Mid-Atlantic/New England area.
On Tuesday I shared with you some work by Jonathan Corum at the New York Times on the 17-year cicadas now starting to emerge back east. (And as I recall from my childhood, I assure you that they are quite loud.) Today we look at an illustration of the cicada life cycle via the Washington Post.
As I discussed the other day about other graphics, there are differences in how the two newspapers are presenting the same topic or subject matter. The New York Times piece concerns itself with the emergence over time of cicadas across the United States and links to historical articles about those events. Here, however, the Washington Post instead explains just how you get a seventeen-year period between emergences.
Additionally, the Washington Post maps near the end are not interactive as in the New York Times piece. But what this allows the Post to do is focus on those broods that impacted the Washington area instead of all those areas likely outside the Post’s core readership.
The Washington Post's explanation of the periodical cicadas
Recently the National Post looked at the results of a Canadian census that identified significant growth in people identifying with the aboriginal populations of Canada. As an American, I am not terribly familiar with Canadian native populations, but if I recall, they are broken into the three groups examined in the infographic: First Nations, Inuit, and Metis. The First Nations are the original tribes of Canada, the Inuit are the natives from northern Canada, and the Metis are the mixed-race persons of native and early European colonisation.
Aboriginal Canada
I find interesting the National Post’s use of network diagrams (the bubbles with lines) to show how the subcomponents form the whole. This as opposed to perhaps a more common form of a tree map or bubbles within a bubble. I would be curious to see or learn about which is the most effective at showing the relationship both in terms of structure (hierarchy) and size (without the datapoints included as labels).

Cicadas are loud. And while some are around every year, there is at least one species that lives for up to seventeen years. They mate every seventeen years. In 2013 we are witnessing the emergence of Brood II, one of the numerous clusters that are synchronised to each other. But when and where have other broods been spotted over time? The New York Times looked at this question last week via an interactive graphic.
Yesterday both the New York Times and the Washington Post published fascinating pieces looking at the difference in the cost of medical procedures. But each took a different approach.
I want to start with the New York Times, which focused at the hospital level because the data is available at that level of granularity. They created a geo-tagged map where hospitals were colour-coded by whether their bills were below, slightly above, or significantly above the US average.
Hospitals across the United States
The ability to search for a specific town allows people to search for their hometown, state, country and then compare that to everyone else. My hometown of West Chester, Pennsylvania is fortunate—or perhaps not—to have several hospitals in the area that charge at different rates. That makes for an interesting story. But I am from the densely populated East Coast and someone from say rural Montana might not have the same sort of interesting view.
Hospitals near West Chester, Pennsylvania
Regardless of the potential for uninteresting small-area comparisons, once you find your hospital, you can click it to bring up detailed statistics for procedures, costs, and comparisons to the average.
Brandywine Hospital's data
All of this makes for a very granular and very detailed breakdown of hospital versus hospital coverage. But what if you want something broader? What good is comparing Brandywine Hospital to some medical centre in Chicago? Neither is reflective of the healthcare industry in the Philadelphia area or the Chicago area, let alone Pennsylvania or Illinois. The Washington Post tackles this broader comparison.
The Post leads off with a hospital-level example from Miami. Two hospitals on one street have vastly different prices. If we knew about this in Miami we could surely find that in the New York Times map. Instead, the Post guides us to that kind of example.
Comparing two hospitals in Miami
But the broader view is the centre of the piece. Using dot plots and filters, the user can compare the state averages for 10 different medical procedures. Fixed to the plot are the minimum and maximum averages along with the national average. And given the Post’s smaller circulation area—the New York Times is national, the Post is less so—there are quick links to states of particular interest: DC, Maryland, and Virginia.
Pennsylvan's averages
The ability to pick different states from the drop down menu allows the user to quickly see differences between states. What is lacking is perhaps a quick view of where all the states are visible so that the user does not have to click through each individual state.
California's averages
Both pieces are very successful at their narrowly-focused aims. Neither tries to do everything all at once, but nor would their designs allow for it. Plotting and filtering all the hospitals could be done in the Post’s style, but it would be messy. The state averages could all be made to colour state shape files, but you would lose the inter-procedure differences, the minimums, maximums, and the averages. In short the two pieces from the two teams complement each other very well, but a weird and hybrid-y cross of the two would be large, cumbersome, and potentially difficult to use without spending a lot of time to design and develop the solution. (Which I imagine they did not have.)
