This visualization fails to do this. This series of circles within circles––blue for the market values of banks in quarter 2 of 2007, before the recent financial meltdown, and green for declined values as of January of 2009––was published by Bloomberg. You would never guess its purpose, however, which was to show that J. P. Morgan’s decline in market value was less severe than all other major banks except one: Santander. This picture of the data doesn’t tell the story clearly, simply, or accurately. The comparative sizes of the circles are far from the comparative market values. Even if the sizes of the circles were accurate, we would still struggle with this chart because visual perception isn’t well-tuned to handle size comparisons, but it is tuned to handle length comparisons,...
...such as the lengths of these bars in my redesign of the chart. We can now easily see that J. P. Morgan lost roughly half of its market value during this period, but the fact that its losses were less severe than all by one bank––Santander––still isn’t obvious. The right addition to the picture, however, such as this one in the bottom half that displays the losses directly, can make this part of the story clear as well.
