Minard's Chart of Napoleon's 1812 Russia Campaign via Google Maps and ProtoVis

I've written before about Minard's chart of Napoleon's 1812 March on Russia, considered by many to be the best chart ever made in that it communicates many levels of detail with an economy of markings.



To read the chart, you should know that Napoleon's Grande Armée starts out as the wide, brown line on the left. 422,000 men crossed the Niemen River to begin the campaign. The Army is marching to the east, left-to-right. As the Army progresses further, soldiers die and the size of the force is reduced, indicated by the diminishing width of the brown line.

You'll also see where two splinter forces leave the main body to cover the supply lines and any possible retreat.

Eventually, a reduced French force arrived in Moscow, which the Russians had abandoned. There was very little food in the city, and fires broke out over several days. Napoleon was forced to retreat, and 100,000 men started marching west (signified by the black column).

Losses continued in their retreat, even as they rejoined the forces left behind. The weather turned very cold (the chart on the bottom shows the temperatures during the retreat). The final column that returned to cross the Niemen River westbound was 4,000 men from Moscow and 6000 men from the units left to cover the retreat.

This was a battle of logistics as well as of tactics; the French Army lost more men to starvation, desertion, typhus, and suicide than to combat. The Army advanced faster than supply trains could manage, and there was no forage available.

Best Mashup of 2009

Minard's chart tells this brutal story with elegance. Until recently, reproductions and redesigns of the information have been paper-based, but new work at Standford University has used a mashup of Google Maps and a visualization tool called ProtoVis to produce a digital presentation of Minard's chart.


The temperature scale presented uses the now obsolete Reaumur scale (°R), the same scale as Minard used.

Click here to see the chart in it's own webpage, where you can scroll, zoom in and out, and look at either Maps or Terrain. It's very well done, and conveys the efficiency of the original along with new tools.

A Failure We Might Learn From

I believe in studying failure rather than success. My favorite wall poster (I have a copy both in my office and in my home) is Minart's chart depicting Napoleon's failure in Russia. Napoleon was such a smart guy, and yet he projected himself directly into this whopping failure.

As I've written before in my review of "The Logic of Failure" (excellent book, btw), there's a lot of failure out there and it's often well documented.

Success, on the other hand, is talked about more but often wrapped in myth and obscurity. Success sells - if you look at the "management" section at a bookstore, there's a lot more "success stories" then "debacle diaries™". It seems like nobody succeeds because of "good luck", usually success is driven by the right blend of personal virtue, a shoeshine, and a ready smile.

Curiously, a lot of failures are attributed to "bad luck" or to other people, and very few failures are assigned to personal flaws, hubris, or bad decisions. You'd think that luck would have a balanced 50/50 impact, but in the literature it seems like luck only causes failures. Anyway, I like to study failures. Here's a true story of a failure from this week's news:

In 1995, a registered nurse named Susette Kelo bought a small, pink, 100-year old clapboard house in the Fort Trumbull neighborhood of New London, Connecticut. New London was (and remains) a deteriorating town that has seen a long time pass since its glory days with the whaling industry. A big fiscal problem for New London is that most of its land is held by three tax-exempt colleges.

 

Hoping to improve the city, New London created a "New London Development Corporation" (NLDC) which planned to seize a 9-acre neighborhood in order to induce Pfizer to develop a 26-acre industrial park. Pfizer would also receive an 80% discount on their real estate taxes for 10 years.

Under the threat of seizure, most homeowners sold to the NLDC. Seven homeowners resisted the seizure in the courts. Susette Kelo became the spokesman for the holdouts, who argued that eminent domain was appropriate for public works — highways, trains, and public health — but not for economic development.

In Kelo v. the City of New London, a 5-to-4 Supreme Court majority opinion held that promoting economic development met the “public use” clause of the Fifth Amendment and supported the condemnations. The NY Times editorial board, by the way, really liked the Supreme Court decision.

In a dissenting opinion Justice Sandra Day O’Connor said, “Under the banner of economic development, all private property is now vulnerable to being taken and transferred to another private owner, so long as it might be upgraded.” Justice Clarence Thomas called New London’s plan “a costly urban-renewal project whose stated purpose is a vague promise of new jobs and increased tax revenue, but which is also suspiciously agreeable to the Pfizer Corporation.”

The houses were destroyed, the families forced to move, and the neighborhood was erased. A local citizen bought Kelo's condemned house for $1 and moved it to another location, where it now bears a sign indicating its provenance:


This is what the peice of land that Kelo's house occupied now looks like:


After the houses were destroyed, nothing happened. No R&D complex, no gentrified condos, no influx of high-net-worth PhDs. Nothing. This week brought news from Pfizer:


Pfizer announced this week their intention to abandon the project and close the offices it has in New London; the homes were razed but the research park and office complex was never built. What happened? There was a change; Pfizer acquired Wyeth for $67 billion, and the NewCo had surplus office space. The corporate priority had shifted. They didn't need that land anymore. From the NY Times:
For its part, Pfizer said it had no stake in the outcome of the Kelo case nor any interest in the development of the land that was acquired by eminent domain, according to a statement provided by a spokeswoman, Liz Power.


Remarkably, Pfizer's exit from New London is synchronized exactly with the expiration of their tax discount. Where are they going? Across the river to Groton, where the discount persists.

From the 11/13 New York Times:
From the edge of the Thames River in New London, Conn., Michael Cristofaro surveyed the empty acres where his parents’ neighborhood had stood, before it became the crux of an epic battle over eminent domain. “Look what they did,” Mr. Cristofaro said on Thursday. “They stole our home for economic development. It was all for Pfizer, and now they get up and walk away.

I mention this for at least these reasons:
  • I really am a student of failure, I think failure teaches more than success.
  • I think this shows what happens when you deal with Corporations. With businesses you can do your due diligence and rely on them; there's often a real person who's name is on the shingle. Generally people are trustworthy if you build the deal right. Corporations, on the other hand, are amoral legal entities chasing continually evolving definitions of profitability, strategy, and their market. Businesses have skin in the game; corporations don't. I'd like to restate this into an expression you may see here again: Business people good; corporations bad.
  • I think this shows what happens when Government (in this case, the City of New London) set up quasi-agencies to do hard things. Government is accountable; the voters select the players, and the voters will fire them at the next election if they screw up. The development corporation had the opportunity to take action at no personal risk, without accountability, and - by the way - they're only successful if change happens. That's a recipe for a crapshoot, and usually these situations are not amenable to those odds.
  • I see echoes of USAirways in this.

Minard's Chart of Napoleon's 1812 March to Russia : Best. Chart. Ever.

Having discussed a misleading chart in an earlier post, I'd like to write about a chart considered by many to be the best statistical chart every made: Charles Joseph Minard's chart of Napoleon's march to Moscow in his Russian campaign of 1812.


Click for larger image, opens in a new window

Beginning on the left at the Polish-Russian border, the width of the thick band shows the size of the Grande Armee at each position. The upper brown line shows the size of the army (422,000 men) as it progresses eastbound to Moscow. When the army turns around to head home, the (decreasingly wide) black ribbon shows the dwindling size of Napolean's army, which is cross-referenced to time and temperature scales. Finally, only 10,000 men return from the misadventure. The chart depicts a brutal chapter in history.

Given any time during the campaign, the chart conveys the army's direction, size, and loss relative to the start; on the retreat, the chart also conveys the timeline, position of the army, and the temperature.

From Wikipedia: Étienne-Jules Marey first called notice to this dramatic depiction of the terrible fate of Napoleon's army in the Russian campaign, saying it "defies the pen of the historian in its brutal eloquence". Edward Tufte calls it "the best statistical graphic ever drawn" and uses it as a prime example in The Visual Display of Quantitative Information. And Howard Wainer also identified this as a gem of information graphics, nominating it as the "World's Champion Graph".

I have blogged elsewhere about the notion of noticing which books a person has more than one copy of, as an indicator of the person's interests. This is a chart that I own more than one copy of, including a version from Tufte presenting the original French chart along with a recent English translation.

That the beauty, efficiency, and elegance of this chart was delivered by a human with a pen, two colors, and paper (and not anything to do with computers, chart wizards, or powerpoint) is a topic for another time.
