title: Python: Venn diagram: how to show the diagram contents?
body: <p>I have the working code below.</p>
  
  <pre><code>from matplotlib import pyplot as plt
  import numpy as np
  from matplotlib_venn import venn3, venn3_circles
  Gastric_tumor_promoters = set(['DPEP1', 'CDC42BPA', 'GNG4', 'RAPGEFL1', 'MYH7B', 'SLC13A3', 'PHACTR3', 'SMPX', 'NELL2', 'PNMAL1', 'KRT23', 'PCP4', 'LOX', 'CDC42BPA'])
  
  Ovarian_tumor_promoters = set(['ABLIM1','CDC42BPA','VSNL1','LOX','PCP4','SLC13A3'])
  
  Gastric_tumor_suppressors = set(['PLCB4', 'VSNL1', 'TOX3', 'VAV3'])
  #Ovarian_tumor_suppressors = set(['VAV3', 'FREM2', 'MYH7B', 'RAPGEFL1', 'SMPX', 'TOX3'])
  venn3([Gastric_tumor_promoters,Ovarian_tumor_promoters, Gastric_tumor_suppressors], ('GCPromoters', 'OCPromoters', 'GCSuppressors'))
  
  venn3([Gastric_tumor_promoters,Ovarian_tumor_promoters, Gastric_tumor_suppressors], ('GCPromoters', 'OCPromoters', 'GCSuppressors'))
  plt.show()
  </code></pre>
  
  <p>How can I show the contents of each of the set in these 3 circles? With the color alpha being 0.6. Circles must be bigger to accommodate all the symbols.</p>
