title: How to obtain generated x-axis and y-axis range in plotly plot?
body: <p>I have a very simple bubble chart, see below. the only thing i need is to be able to get the range (or the min and max) or the x and y axis generated.</p>
  
  <pre><code>trace = go.Scatter(
      x=df_test['total_points_mean'],
      y=df_test['total_points_std'],
      mode='markers',
      text=df_test['play_maker'],
      marker=dict(size=df_test['week_nunique'],
                  color = df_test['week_nunique'],
                  showscale=True)
  )
  
  layout = go.Layout(title='Scatter Plot')
  fig = go.Figure(data=[trace],layout=layout)
  </code></pre>
  
  <p>From the resulting plot, the min and max of the x axis seems to be around ~10 and ~29, but i need a way to generate the exact value of the axis range.</p>

  <p>Is there a way to access the generated axes range?</p>
