title: Folium map issue in PyCharm
body: <p>I am using Pycharm and the folium maps are not being displayed. My code is as follows:</p>
  
  <pre><code>import folium
  from folium import plugins
  import pandas as pd
  import matplotlib.pyplot as plt
  import seaborn as sns
  from IPython.core.display import display, HTML
  
  m = folium.Map([52.5, 2], zoom_start=5.5)
  display(m)
  </code></pre>
  
  <p>But I am able to save it as html and it is correctly displayed in html.</p>
  
  <pre><code>m.save('aee.html')
  </code></pre>
