1. Overview the development of company It's easy to find that the company is growing since 2015,but the increasing rate is not obviously. 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. It seems that the management philosophy is changed.
2. Overview the development of company(2) There are no meetings in few dates of 2015. The data set only contains the information after 2015-05. The number of purchases show us a increasing trend in general.
3. Overview the development of company(3) The number of calls, emails and purchases is quite stable. Although the changing of purchases shows us a little decreasing, the development of company is increasing in general. Because the changing of meeting has strong influence. It should be easy for the employee who work for Kasios to find that there are more and more meetings from 2016 to 2017.
4. Overview the development of company(4) Is't is to find that dramatically increasing at first. The phenomenon might be caused by the incomplete data in 2015-05 or something I don't know happen.

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.
2. Explore the company(2) <br)Bigger size of points indicate how important they are in the suspicious group. It's easy to find out that Linds and Richa might be the important guys in the group. 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.
