title: How to add several graphs to a single tab using plotly express with python
body: <p>I have a script that producing <code>5</code> different <code>graphs</code> that I want to present in one <code>web page</code>.
  I use <code>python</code> with plotly express and define <code>pio.renderers.default = "browser"</code>.
  The problem is that each graph is open in a new tab, and I want only one tab that I could share. 
  My script contains two separate data frames:</p>
  
  <pre><code>import pandas as pd
  import plotly.express as px
  import plotly.io as pio
  pio.renderers.default = "browser"
  
  df1=pd.read_csv('data1.csv')
  df2=pd.read_csv('data2.csv')
  
  fig = px.bar(df1,x1, y1,color='a',barmode='group')
  fig.show()   
  fig = px.line(df2,x2, y2,color='b')
  fig.show()   
  </code></pre>
