The given chart depicts the proportion of a car factory’s total sales each year in four different continents including Asia, Europe, South America, and North America between 2006 and 2010.
To begin with, the percentage of total sales of the Asia car factory started at 30% in 2006 and increased to 34% in 2007. It then remained stable in the next year and peaked at 50% in 2010.

The figure continuously went up and finished at below 10%.
Moving on to the other categories, the percentage of the Europe car factory’s total sales started at about 30% in 2006 and it then rose by 6% in the next two years. However, the figure witnessed a decrease to around 30% in the last year. If we look at North America, the trend is similar. In the first year and last year, the proportion of total sales of the North America factory was the same, which was 10%. The figure experienced a rapid decline from 2007 to 2009 and hit the bottom at below 5% in 2009.
Overall, it can be seen that the total sales of the car factory in Asia experienced an upward trend while the opposite was true with South America. Besides, there was a fluctuation in the total sales of the car factories in South America and North America.
