The bar graph shows the number of Internet users in the three countries between 1998 and 2013 with the world average.
Overall, it is clear that Internet users in the three countries dramatically increased and also the world average continued to grow but the gap between the number of Internet users in the three countries and the world average widened over the 15 years.
Looking at the graph more closely, one can see that in 1998, the number of Internet users in Canada was the largest at about 27,000 and Canada was followed by Denmark, which had nearly 23,000 Internet users. Greek Internet users were less than the world average that year. In 2003, the number of Internet users in Denmark stands out as the highest figure, surging to about 80,000 and the growth was slow from 2003 to 2013. Canadian Internet users also rose rapidly until 2003 and afterward it slowly went up. Greece gained about 20,000 new users every five years and the world average ascended continually as well.
