SAS’s ODS Graphics technology brought the concept of layer into data visualization. We can use those SG procedures to do many tricks. Previously in SAS, a map has to be drawn from its GMAP procedure. Now we can simply use 3-4 lines of codes to sketch some maps by the scatter statement in PROC SGPLOT, such as North America or Asia.

ods html style = money;
proc sgplot data = maps.namerica noautolegend;
scatter x = x y = y / group = id markerattrs=(size=1);
xaxis grid label = ' '; yaxis grid label = ' ';
run;
proc sgplot data = maps.china ;
scatter x = x y = y /markerattrs=(size=2);
xaxis grid label = ' '; yaxis grid label = ' ';
run;



We can apply it to single countries, like China or India. For India, the aspect has to be modified a little. It can be aslo done by PROC SGSCATTER. My friend Xiangxiang has a great tutorial for this procedure.

ods html style = harvest;
proc sgplot data = maps.asia noautolegend;
scatter x = x y = y / group = id markerattrs=(size=1);
xaxis grid label = ' '; yaxis grid label = ' ';
run;

ods html style = htmlbluecml;
ods graphics on / width=6in height = 6in;
proc sgplot data = maps.india;
scatter x = x y = y /markerattrs=(size=2);
xaxis grid label = ' '; yaxis grid label = ' ';
run;
ods graphics / reset;
Thanks to SAS’s ODS group, those SG procedures always give me limitless fun
