venny4py 1.0.4

Python3 package to create Venn diagrams with 2-4 sets.

Venny4Py

Simple Venn diagrams for Python 3, up to 4 sets (for more than 4 sets it is better to use UpSet plot). It will take as input a dictionary of 2-4 sets and produce a venn diagram and a txt file with element intersections.

Dependencies:

• itertools
• matplotlib

Installation:

pip install venny4py

When installed, import:

from venny4py.venny4py import *

#dict of sets
sets = {
    'Set1': set(list("Harry Potter")),
    'Set2': set(list("Hermione Granger")),
    'Set3': set(list("Ron Weasley")),
    'Set4': set(list("Severus Snape"))
}
    
venny4py(sets=sets)

Parameters:

• sets - dictionary of sets (required)
• out - directory to output files, default current directory
• asax - if diagram should be plotted as subplot, then provide matplotlib ax here. Default is 'False' which will plot new figure
• ext - image extension, default is 'png'.
• dpi - image resolution, default is 300 dpi.
• size - image size in inches, default is 3.5. If using custom ax through "asax" parameter, specify approximate size of subplot in inches since fontsize is dependent on this parameter.
• colors - set of colors for each set, default is "bgrc".
• line_width - control line width.
• font_size - control font size.
• legend_cols - number of legend columns, default is 2.
• column_spacing - column spacing in legend, default is 4.
• edge_color - edge colors, default is 'black'.
• alpha - fill opacity of the sets, default is 0.3.
