The line graph shows data on the number of visits abroad by British people and visits from overseas residents to the UK, while the bar chart provides the figure of the favorite countries travel by UK residents.

It is clear from the graph that the visits made by UK residents are more than the visits made to the UK.

The trend for oversea visitors climbed steadily in the period of 20 years, from 10 million visits in 1979 to over 25 million in 1999. On the other hand, the journeys made by British had a significant increase of 41 million trips in the same period, from 11 million to 52 million.

In 1999, over 12 million UK residents visited France, which was the most popular country of all, while a lesser number of 9 million travelers went to Spain. Other countries such as the USA, Greece, and Turkey totaled(can I use accounted here?) for approximately 9 million visitors.

Are the following sentences correct?
Other countries constituted approximately 9 million visitors.
Other countries comprised approximately 9 million visitors.
Other countries consisted approximately 9 million visitors.

hahah, no matter. This looks nice.

It is clear from the graph that the number of visits made by UK residents is greater than the number of visits made to the UK.

...which was the most popular country destination of all, while a ...

Other countries such as the USA, Greece, and Turkeyaccounted for approximately 9 million visitors.
Yes! accounted

Are the following sentences correct?
Other countries constituted approximately 9 million visitors.-- no, this would mean the countries were the visitors.
Other countries comprised approximately 9 million visitors.--- no, this means the same as constituted, and it seems wrong.
Other countries consisted approximately 9 million visitors.--- no, it would be this:
Other countries consisted of approximately... you use OF. But that is still not correct here. Something that consists of something else is made up of it.

:-) you are right about 'accounted."
