The line chart compares the number of international conferences held in three different cities between 1965 and 2010, at 10-year intervals. Looking at the illustration, it is immediately evident that the number of conferences held in City C increased significantly during this period, while the figures for City A and City B fluctuated widely.
In 1965, City A dominated the chart with 35 conferences, which was 3 more than City B, while City C had no international conferences. By 1995, City C had climbed significantly to over 27 conferences and had overtaken City A to become the city with the highest number of international conferences.
By 2010, after a dramatic increase, the number of international conferences in City C had continued to experience exponential growth, reaching around 30 conferences. In contrast, the numbers for City A and City B gradually declined to about 20 and 25 conferences, respectively.
