Alaska Airlines

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.

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.

Which Beaches Are Open for the Start of Summer?

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.

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.

Your State’s Highest Paid Public Employee

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.

More Cicadian Rhythms

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.

Aboriginal Canada

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.

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).

Cicadian Rhythm

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.

Comparing Medical Cost Comparisons

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.

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.

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.

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.)

On Holiday in Ganister

Well, actually, your author is driving back from Ganister today. Unfortunately, while on holiday I was not working (nor was I planning to.) So while I could of run silent today, I wanted to share with all of you again a project I created last year about my return drive from Ganister. For all of who familiar with the piece, I apologise for my re-posting of previous work. For those of you unfamiliar with the work or with Ganister and its distance/remoteness, enjoy. (It’s full-size, so no click-for-higher-resolution.)

Nate Silver Predicts the Presidential Election

Of 2048. Well, kind of. Lately the country has been talking a lot about immigration and its impacts because of this bipartisan desire to achieve some kind of result on an immigration bill working its way through the Senate. One of the common thoughts is that if we legalise a whole bunch of illegals or document most of the undocumented (I’ll leave the language for you to decide), the new American citizens will overwhelmingly vote Democratic and there goes the Republic(an Party).

Nate Silver—yes, that Nate Silver who accurately predicted the presidential results and a whole bunch of other stuff too—looked at a more complex and more nuanced set of demographic variables and found that the aforementioned argument greatly oversimplifies the results. The problem is not entirely the entry of newly documented or illegal workers. Instead, there are systemic demographic issues.

So here comes the New York Times with an excellent data explorer and forecast modeller. You can set the year to examine and then set the results of the immigration debate with how many immigrants are made legal/documented and then how many of them vote. After that you can begin to adjust population growth, voting patterns, &c. to see how those affect the elections. (The obvious caveats of acts of god, party platforms, candidates, &c. all hold.)

2048 Results
2048 Results

The fascinating bit is that if you keep the demographic patterns as they are currently, adjusting the immigration factors at the outset have very little impact on the results. The country is moving towards the current Democratic platform. Even if 0% of the undocumented/illegal immigrants become documented/legal, and if 0% of 0% vote, the result is still a landslide for the Democrats. The real changes begin to happen if you adjust the population growth rates of the legal/documented citizens and voters. But those patterns/behaviours are a lot more difficult to adjust since you can’t legislate people to have more babies.

All in all a fascinating piece from the New York Times. The controls are fairly intuitive, drag sliders to adjust percentages. The sliders have clear labels. And the results on the map are instantaneous. Perhaps the only quirk is that the ranges of the colours are not detailed. But that might be a function of forecasting the data so far into the future and having growing ranges of certainty.

Asian Immigration

Today I have more immigration-related information graphics and data visualisation for you. Earlier this week the New York Times looked at immigration to California, but this time the focus was on Asian population growth and not Hispanic. The graphic here supports an article looking at where the growth has been focused in California. And given that emphasis, the map accompanying the article makes sense. And as the reader can clearly see, much of that growth has been centred in the San Gabriel Valley and Orange County.
