How to edit the label font sizes on building a treemap with squarify in Python?

I am using a squarify package in python, codeLink, to draw a treemap, wikiTreemapArticle. Based on this example, I can produce a treemap, but I am unable to see how the fontsizes of the labels in the squares can be modified. The essential line in the script is:

ax = squarify.plot(countryPop, color=colors, label=labels, ax=ax, alpha=.7)

From here I cannot add the 'fontsize' attribute. How would I change the sizes of the labels?

#Fonts demo (kwargs)
#Set font properties using kwargs.

#See Fonts demo (object-oriented style) to achieve the same effect using setters.


squarify.plot(sizes=volume, label=labels,text_kwargs={'fontsize':10, 'fontname':"Times New Roman Bold",'weight':'bold'},color=color_list, alpha=0.9)

Update: There is now a possibility to change the fontsize (squarify==0.3.0 or higher) via the text_kwargs parameter:

ax = squarify.plot(countryPop, color=colors, label=labels, ax=ax, bar_kwargs={'alpha':.7}, text_kwargs={'fontsize':10})

the squarify works on matplotlib pyplot so you just need change de font size of pyplot.

I use to do the following thing on my plotting codes. 

SMALL_SIZE = 13
MEDIUM_SIZE = 18
BIGGER_SIZE = 23

plt.rc('font', size=MEDIUM_SIZE)          # controls default text sizes
plt.rc('axes', titlesize=BIGGER_SIZE)     # fontsize of the axes title
plt.rc('axes', labelsize=BIGGER_SIZE)     # fontsize of the x and y labels
plt.rc('xtick', labelsize=MEDIUM_SIZE)    # fontsize of the tick labels
plt.rc('ytick', labelsize=MEDIUM_SIZE)    # fontsize of the tick labels
plt.rc('legend', fontsize=SMALL_SIZE)    # legend fontsize
plt.rc('figure', titlesize=BIGGER_SIZE)   # fontsize of the figure title

This way you can change any font of your plot, including in the squarify treemap plot.
