Please help me with my essay

My essay:

The line graph plots the number of British children who took part in three different types of sports (football, athletics, and swimming) between 2008 and 2014.

Overall, football was far more popular than athletics and swimming. More children participated in each of the three sports in 2008 compared to 2014, with athletics having the largest increase in popularity.

In 2008, there were approximately 8 million British children playing football, 2 million practicing swimming, and less than 1 million doing athletics. Participation in athletics and football remained relatively stable over the next two years, while that of swimming increased by about 0.5 million. Between 2010 and 2012, there was a surge in athletics’ popularity, surpassing swimming participation in 2011 at 2.5 million and reaching its peak of about 5 million in 2012. Over this period, the number of children who played football rose to approximately 9 million and then remained around this figure until 2014. While the popularity of athletics decreased slightly in 2014, with just under 5 million young players, it was still more popular than swimming, whose participation numbers rose almost linearly to 3 million in 2014.
