I've done a Google Ngrams API that generates plots in XKCD style here:

https://github.com/econpy/google-ngrams

and a webapp version with slightly more advanced XKCD tweaks here:

http://xkcd.culturomics.org

Everything starts with matplotlibs xkcd lib but has been tweaked to produce plots based on the output of the Google Ngram Viewer.
