When it comes to purchases, the number of 2016 and 2017 is similar.Although the increasing rate of emails and calls from 2016 to 2017 is quite low, the number of meeting growing fast over the time.

1. Explore the company
To locate the suspicious in the larger group,I set node.csv as node which represent all people who used to communicate with suspicious from 2015 to 2017. On the other hand, I regard sus.csv as edge,which represent suspicious file provided by insider. It's easy to find out where the suspicious are. Although the file didn't tell us any details about the employee. I can speculate what status they are according to the number of emails,calls,meetings and purchases the employ is recorded. For example, those who received most emails in a year should be a management.

Furthermore, it's quite interesting to find that there are some outliers in the network. They are far from the central and the size of the point is quite small. It means that they only communicate with suspicious few time.
