title: change linewidth in chord plot
body: <p>I want to plot a chord plot like the following:</p>
  <p><a href="https://i.stack.imgur.com/0QF02.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0QF02.png" alt="enter image description here" /></a></p>
  <p>With chord linewidth = some value associated with each chord.
  Curently am using an example <a href="https://www.python-graph-gallery.com/406-chord-diagram_mne" rel="nofollow noreferrer">taken from here</a>, however I am unable to modify linewidth.</p>
  <ul>
  <li>how do i modify linewith?</li>
  <li>is there another library that can work?</li>
  </ul>
  <pre class="lang-py prettyprint-override"><code># pip install mne_connectivity
  from mne_connectivity.viz import plot_connectivity_circle
  import numpy as np
  import pandas as pd
  N = 8
  node_names = [f&quot;N{i}&quot; for i in range(N)]
  con = np.random.rand(N,N)
  fig, axes = plot_connectivity_circle(con, node_names,colormap='Blues',
      facecolor='white', textcolor='black', 
      linewidth=10 )  #### CONTROL LINEWIDTH HERE 
  fig.show()
  
  </code></pre>
