It is very easy to generate geolocation charts of website accesses by using shell scripts based on access_log. The following document offers a way to generate a datafile containing the number of hits based on all the existing ccTLDs at the current time of writing.

What this script does is to go through the access_log of the webserver and extract the IP addresses of the page hits. After that, it performs a reverse DNS lookup on the IP addresses to determine the country of origin. While doing that it keeps a score of the TLDs matching the IPs, incrementing the old value every time a new lookup matches a TLD. After the whole access_log is examined, the script dumps all the data to a file called stats.dat which you can use further and generate charts.

The output format is given by the following line:

  printf "%s = %d\n" ${TLDS[$TLD]} ${SCORE[$TLD]} >> stats.dat

which can be changed, for example to obtain a CSV datafile.

The result of the above formatting is the sample output:

...
wf = 0
ws = 0
ye = 0
yt = 0
...
