title: How to break a long line in a hover text Plotly?
body: <p>I have a hover text that contains a long line (about 200 characters). The problem is that it becomes a long rectangle through the whole figure and it is not possible to see the complete text because it cuts.</p>
  
  <p>My data is in a dataframe. I am plotting x and y and just adding a z variable that contains description in the hover text. </p>
  
  <p><a href="https://i.stack.imgur.com/CixqN.png" rel="noreferrer"><img src="https://i.stack.imgur.com/CixqN.png" alt="Picture of my plot"></a></p>
  
  <p>Is it possible to adjust the high and width of the text box? Or could I break the text in several lines?</p>
  
  <p>This is my code at the moment:</p>
  
  <pre><code>fig = make_subplots(rows=2, cols=1,column_widths=[1], 
                      subplot_titles=["A", "B"])
  fig.add_trace(
      go.Scatter(
          x=df.varA,
          y=df.varB,
          hovertext = df.varC,
          marker=dict(color='darkblue'),
          mode = 'markers'
      ), row=1, col=1)
  
  fig.add_trace(
      go.Scatter(
         x=df.varA,
          y=df.varB,
          hovertext = df.varC,
          marker=dict(color='darkblue'),
          mode = 'markers'
          ), row=2, col=1)
  
  
  fig.update_layout(barmode='stack',showlegend=False, height=900, width=1000,title_text="Example")
  fig.show()
  </code></pre>
  
  <p>Please help me :) </p>
