Basic GMAT Commentary On This Clustered Bar Chart (Graphical Interpretation) GMAT Integrated Reasoning Question
This integrated reasoning GMAT quesiton involves a clustered bar chart. It's just like a regular bar chart, except for each column entry - instead of having 1 bar, it'll display multiple bars. Usually each of the clustered bars represents a different time period.
In this case, each set of bars corresponds with a particular country. Each set of bars consists of 3 separate bars - 1 for each year 2009, 2010, and 2011. The left side shows the GDP in metrics of $ per capita. So you can effectively say that the graph shows how much GDP was generated per person in the specified countries for each of the 3 years shown.
