Please review my essay

topic: the chart below shows the main reasons why people choose to make or break friendship connections on a popular social media site.

The bar chart gives information about five primary reasons that users of a popular social networking site decide to add or remove an account as a friend. Specifically, it plots the percentage of those choosing one or more of the reasons.
Overall, the majority of users friend a profile because they know the owners in real life or are friends with each other, the former reason having the highest percentage. Only a minority choose the other three reasons. In comparison, all five reasons why they unfriend an account are more equally common, in that the gap between the ones that received the highest and lowest value is much smaller.

Would you mind giving me some other ways to write the introduction paragraph and some other ideas for the overview, please? Thank you so much.
