The easy way to ielts writing academic Module

Note that there is no need to write about every single piece of data
on a trend. However, it is essential to compare the beginning and
ending points, significant changes, and turning points (where the
trends change their directions).
This type of writing 
does not
 require a conclusion.
Sample writing

The line graph compares the percentage of using two different means of
transportation in Vancouver between 1990 and 2015.
Overall, the percentage of traveling by car had a dramatic increase while the
figure for commuting by bus significantly declined over the period.
Based on the statistics, traveling by car stood at roughly 25% in 1990,
whereas almost 65% of Vancouver’s population considered commuting by
bus. Over the next ten years, these numbers had drastic changes and
ultimately met in the year 2000, when the trend for taking the bus went
down gradually to approximately 45%.In contrast, the figure for traveling
by car witnessed a significant growth to the same amount as the other trend
simultaneously.
To draw a comparison, the figure for traveling by car had a steady rise to
reach the highest point with 80% in 2015. In contrast, the percentage of
people who took a bus noticeably dropped to nearly 30% at the end of the
given period.
