Plotting on a geographical map the provenience of our patients

I am trying to put on a Italian geographical map a dot reporting the provenience ('provincia') of our patients. Ideally, the dot size should be proportional to the number of patients coming from that 'provincia'. An example of the list I would like to plot is the following.

MI  8319
CO  537
MB  436
VA  338
BG  310
PV  254
CR  244
NO  210
RM  189
CS  179

In the first column there is the 'provincia' code: MI (Milano), CO (Como), MB (Monza-Brianza), etc. In the second column there is the number of patients from that 'provincia'. So the output should be an Italian political map where the biggest dot is around the city of Milano (MI), the second biggest dot is near the city of Como (CO), the third one is around the city of Monza-Brianza (MB),etc. Is there any package that could do the plot I am looking for? I found a tool that could do the job here, but apparently they expect that I load the geographical coordinates in order to do the plot.
