The bar graph shows the global sales (in billions of dollars) of different types of digital games between 2000 and 2006.
Here's the first half of my model answer, the introduction and overview:
The bar chart compares the turnover in dollars from sales of video games for four different platforms, namely mobile phones, online, consoles and handheld devices, from 2000 to 2006.
It is clear that sales of games for three out of the four platforms rose each year, leading to a significant rise in total global turnover over the 7-year period. Sales figures for handheld games were at least twice as high as those for any other platform in almost every year.
What examples of paraphrasing can you see in my introduction? Which two main points did I choose for my overview?
