Creating Venn Diagrams with Categorical Data- matplotlib_venn

Question

I'd like to use Python 3 to make a Venn diagram to show categorical data. If I do, say

  Rosy = ["chocolate", "chips", "cake", "sweets"]
  Steven = ["chocolate", "crisps", "nuggets"]

  venn2([set(Rosy), set(Steven)])
  plt.show()

Then I get a diagram with the number of entries corresponding to each segment but what I'd like is the actual entries in each segment (i.e. chips, cake sweets in the just Rosy bit, chocolate in the intersection and crisps and nuggets in Steven's bit). Is there any way of doing this using matplotlib_venn?

The best way that I found is something like this:

set1 = set(['A', 'B', 'C', 'D'])
set2 = set(['B', 'C', 'D', 'E'])

v = venn2([set1, set2], ('Set1', 'Set2'))
v.get_label_by_id('10').set_text('\n A')
v.get_label_by_id('01').set_text('\n E')
v.get_label_by_id('11').set_text('\n \nB \nC \nD')
plt.show()

Just create functions that generate the texts from set1 & set2 for set_text on the fly and it's done.
