Well, you can assign attributes to vertices in C by using the
experimental C attribute handler (which allows string and numeric
attributes only); more details are to be found here:

http://igraph.sourceforge.net/doc/html/ch09s02.html

However, the built-in layout algorithms do not take vertex sizes (or
any other attribute) into account, so setting a "size" attribute won't
help if you are using the built-in layout algorithms. Neither would it
help from the R or Python interfaces as they just call the C layer. Of
course if you are implementing your own layout algorithm, you can make
use of vertex attributes however you want.
