  • If you are not familiar with those kinds of diagrams, they are a little hard to read at a first glance. It took me a few minutes until I understood, that "Total" is a company. Therefore the graphic made no sense at first. Of course, if you have the graphics embedded in an article this confusion would not happen at all. But still, if you have to study a graphics in a news paper (and not a scientific paper) for one or two minutes, just to understand it, you may just skip it. So in the context of a simple news paper this diagram may be a little to complicated.
  • The y-axes shows the growth rate of the companies. This is quite easy to understand. What could be a little irritating are the circles that represent the total production of the year. At a first glance it looks like the circles are related to values of the y-axes, but they are absolutely not (only the center of the circle is relevant). The size of the circle represents information which is absolutely independent from the y-axes.
  • The size of the circles and the growth rate (location on the y-axes and numbered value) alone don't really give you a hint, how the amount of production was in 2002. You can only use the size of the circles to compare this year's production of every company with all other. But wouldn't it also be interesting if you were able to compare the oil production for each company with its own production from 2002? Of course, the growth rate gives you exactly this information, but not in an eye-catching way. It would be, if you had a second circle for each company in the background (with the same center) in another color. Now we would have the size of the circles, that shows you the production amount, the second circle in the back, that gives you an idea how the production amount of each company has changed and the position on the diagram which makes it easy to compare the growth rates of one company with all others. The advantage of this redundant information is the easier way of comparison - the disadvantage is that it maybe makes the diagram even harder to understand at first ('cause there is one more information layer).
