Patient flow Sankey Diagram

Hi all,

I wanted to create this nice graph created by @Jay54 as shown on these links:

Outside-the-box: Circle link graph - Graphically Speaking (sas.com)

Outside-the-box: Directed circle link graphs - Graphically Speaking (sas.com)

I have a data of patients who visit a certain clinic, I will like to display this just like in the links above but vice-versa. This means in my case they are moving from their residents to the clinic.

I tried using the method @Jay54 used but I still need some help

data patientflow;
  input From $18. To $8. LinkCount ;
  datalines;
AAAAAAAAAAAAAAAAA   clinic	11
BBBBBBBBBBBBBBB	    clinic	5
DDDDDDDDDDDD	            clinic	30
EEEEEEEEEEEEEEEEE   clinic	2
FFFFFFFFFFFFF	            clinic	7
GGGGGGGGGGGGGG	   clinic	2
HHHHHHHHHHHHH	   clinic	11
IIIIIIIIIIIIIIII                           clinic	2
JJJJJJJJJJJJJJJJJ            clinic	25
KKKKKKKKKKKKKKK	   clinic	2
LLLLLLLLLLLLLLL	           clinic	 1
MMMMMMMMMMMM	   clinic	48
NNNNNNNNNNNNNN	   clinic	1
OOOOOO(clinic location)    clinic	500
PPPPPPPPPPPPP	           clinic	1
QQQQQQQQQQQQQQ	   clinic	3
RRRRRRRRRRRRRRR    clinic	1
SSSSSSSSSSSSSSSSS  clinic	1
TTTTTTTTTTTTTT	           clinic	1
UUUUUUUUUUUUUUU	   clinic	3
VVVVVVVVVVVVV	            clinic	7
WWWWWWWWWW	   clinic	7
XXXXXXXXXXXXXXX	   clinic	165
;
run;

please note that OOOOOO is the region where the clinic is located that is the reason why the number of cases is in this region very high. The names of the regions are quite long and the arrows should be coming from the different regions and ending at OOOOOO

I will appreciate any help or an alternative solution. Thanks

I know this isn't the exact same graph, but one of my macros might be of interest.

For a Doctor/Patient type Provider network, another layout could be as shown in this post. Node locations are pre computed by some other means.

Or, sometimes I have seen simple vertical diagrams with Providers on left side and Consumers on right side with links.

@JeffMeyers yes, thanks. I saw your code and have being tring to use it as well, but am still not getting it

@Jay54 thanks for the link, I think that will be more usefull for networking. I need something to show patients moving from one place(their residence) to the other(to the clinic)
