A much better chart, favored by statisticians, is the following scatter plot, which brings out insights from the data.
- The 10 companies fall into three groups: Giants (Exxon Mobil, Royal Dutch/Shell, BP, Walmart), Big and Mean (GE, Total, Toyota) and Big and Fat (Ford, DiamlerChrysler, GM).
- Giants have revenues over $270 billion, among them the oil companies are more profitable than Walmart, even though it has the highest revenues.
- Big and Fat consists of auto companies with big revenues but low profit margin.
- The ranking and relative size of revenues can be read off the horizontal axis. Similarly for profits on the vertical axis. So both bivariate and univariate distributions are available on one chart.
This chart is not without problems. It is difficult to place the data labels without obstructing readability. I placed the labels where they don't interfere with any reader tracing dots to the axes, effectively in the northeast quadrant of each dot. I omitted the country labels so as not to clutter the space. I used color to further separate the dots from the labels. I also sacrificed printing every data value for readability, assuming that the reader's interest in magnitude is not absolute.
