The provided graph offers information about the figure of visitors to four global museums, namely the Louvre, Vatican Museum, Shenzhen Museum and London Science Museum over a 35 year-period from 1980 to 2015. Looking from a general perspective, it is clear that the museums showed an upward trend except for the London Science Museum.
Moving to the details, the number of people who attended the Louvre accounted for about 8 million at the beginning of the period, which then experienced a significant increase to 9 million in 1995. Having fallen considerably to just above 8 million in 2000, the number of visitors rose gradually to just under 10 million by the end of the period. If we look at the number of spectators, the Vatican Museum experienced a sharp rise throughout the period. It started at just under 5 million and peaked at just below the final number of the Louvre.
Turning to the Shenzhen Museum, it began at around 4 million in 1980, meaning it initially welcomed far fewer visitors compared to the other museums. There was a gradual decline to 3 million in 2000, until it increased significantly to just under 4 million in 2015. Regarding the London Science Museum, the figure of guests remained constant at 4 million for the first five years of the period, and then fell sharply to 3 million in 1990. The number of visitors both to the Shenzhen and London Science Museums crossed with each other to 3 million over 10 years from 1990 to 2000, which then the London Science Museum had dropped steadily to just above 2 million in 2015.
