The data given in the line graph illustrates the number of X virus cases in Australia for over 35 years from 1960 to 1995.
In summary, there are distinct trends in all figures that are displayed in the chart. As can be seen from the line chart, Australia witnessed a dramatic increase of 450 from 50 to 500 in the period 1960 - 1975 in the incidence of X virus disease. After stabilizing at 500 during the phase 1975-1980, the number of X infections declines slightly by approximately 100 to around 400 in 1985. From 1985 to 1990, there was a sharp fall of over 400 to exactly 0 in the quantity of the disease. Moving on to the last five years, what is worth mentioning is that the number of cases remained at the same level at 0. It meant Australia had not recorded any more cases about this X virus.
