SAS Visualise network relationships between individuals

[Sean_OConnor]

Folks,

Would anyone be able to provide some helpful code as to how I can visualize different relationships between individuals please? Below is some sample data I generated.

data sample;
   infile datalines delimiter=''; 
   input Person_1 $8. Person_2 $9.;
   datalines;
1099161F	0271089L 
1099161F	
1099161F	0924825s
021089L		1099161F 
021089L 	0325554F

Any kind of advice as to how to generate a relationship network graph would be very helpful.

You can accomplish this with PROC SGPLOT and a bit of data prep.  

First, you'll need to reorganize your data into a series of nodes (thinking of each person as a numbered node) and the position of each node.  Then you need records that show which nodes link to each other.  Usually this requires two data sets: one with the nodes, and one with the links.
