Re-Visions
of Minard
In
1862, a French engineer named Charles Joseph Minard created "one
of the most stunning multidimensional graphical representations
of human folly" when he drew a flow-map that depicted the devastating
results of Napoleon Bonaparte's Grand Army's invasion of Russia
in 1812. This two dimensional page of pen and ink drawing displays
six dimensions of descriptive data. It has been called the "best
statistical graphic ever produced." [Tufte, 1983]
<snip>
The thick band in the middle describes the size of Napoleon's army,
422,000 men strong, when he began the invasion of Russia in June
of 1812 from the Polish-Russian border near the Niemen River.
As the army advances, the line's thickness reflects its size, narrowing
to reflect the attrition suffered during the advance on Moscow.
By the time the army reached Moscow (right most side of the drawing),
it had been reduced to 100,000 men, one-quarter of its initial size.
The lower line depicts the retreat of Napoleon's army, and the catastrophic
effect of the bleak Russian winter. The line of retreat is
linked to both dates and temperature at the bottom of the graphic.
The harsh cold reduced the army to a mere 10,000 men by the time
it re-crossed into Poland. In addition to the main army, Minard
characterizes the actions of auxiliary troops who move to protect
the advancing army's main flanks. [Long, 2003]
