The graph illustrates the usage of water globally during the time period 1900 to 2000. The agriculture sector shows the most prominent rise during this period from 500 km3 to 3000 km3. Meanwhile, the industrial and domestic sectors too increased their water usages from 1950 onward, though not as strikingly as the agriculture sector. Domestic usage only reached 300 km3 at the start of the 21st century whereas industrial usage surged further till it reached 1000 km3. Using this graph, we can conclude that the global water usage has increased as time went by.
The table summarizes the correlation between the two countries, Brazil and Congo, and their water consumption for the year 2000. Firstly, we can see that Brazil has a population almost 30 times greater than Congo. Similarly, the irrigated land and water consumption of Brazil is vastly greater than Congo; Brazil has irrigated 26,500 km2 of it's land while by Congo, only a mere 100 km2. This explains why the water consumption per person in Congo is low, considering it's only 8 m3 which is a far cry from the 359 m3 consumed per person in Brazil. From these statistics,we have reached the conclusion that there is a positive correlation between the area of irrigated land and water consumption per person.

Personal comments: I suppose I ended up sounding rather mediocre but it is a first try, after all. Anyway I really have to buff up on my vocabulary and pick my words properly without rambling on so much.
