The line graph compares amounts of oil concumption, in million barrels per day, in four different countries between 2002 and 2015.
The overall pattern suggests that the Country A was the main consumer of oil, compared with other three counties that were substantially lower throughout the whole period. Nevertheless, there was no noticeable changes, and counties remained relatively at the same rate as in 2002.
The most salient figure, Country A stood at roughly 8 million barrels of oil per day in 2002, which was four times as much as Country C use in the same year. Despite the marginal decline in 2011, first country increased by almost 1 million barrels per day in 2015, while in Country C the consumption of oil maintained the same rate of around 3 million barrels per day.
Consumption in Country B demonstrated some fluctuations over the period, and peaked at 3 million barrels per day in 2010. However, both Country B and Country D experienced the downward trend, declining to almost half of a million barrels per day in 2015.
