title: Cartopy - multiple arrows using annotate
body: <p>Using <a href="https://stackoverflow.com/questions/25416600/why-the-annotate-worked-unexpected-here-in-cartopy">this solution</a> as base, is it possible to create multiple arrows emanating from the same source to different targets? e.g. Delhi -> Beijing (116.4, 39.9), Delhi -> Cairo (30.0, 31.2), Delhi -> Tokyo (35.6, 139.6)?</p>
  
  <p>When I repeat the code below, I only get the first arrow.</p>
  
  <pre><code>#Dehli - Beijing  
      ax.annotate('Beijing', xy=(116.4, 39.9), xycoords=transform,
              size=40,
              )
  
      ax.annotate('Delhi', xy=(113, 40.5), xytext=(77.23, 28.61),
              size=40,
              arrowprops=dict(facecolor='red', ec = 'none',
                              arrowstyle="fancy",
                              connectionstyle="arc3,rad=-0.2",
                             ),
              xycoords=transform,
                 )
  
  #Dehli - Cairo  
      ax.annotate('Cairo', xy=(-6.26, 53.34), xycoords=transform,
              size=40,
              )
  
      ax.annotate('Delhi', xy=(113, 40.5), xytext=(77.23, 28.61),
              size=40,
              arrowprops=dict(facecolor='red', ec = 'none',
                              arrowstyle="fancy",
                              connectionstyle="arc3,rad=-0.2",
                             ),
              xycoords=transform,
                 )
  </code></pre>
  
  <p>Alternatively, is there a way to put .annotate into this expression which I'm using at present to draw connecting lines. I've tried to no avail:</p>
  
  <pre><code>#Coordinates
  lon_dehl, lat_dehl = 116.4, 39.9
  lon_beij, lat_beij = 77.59, 12.97
  lon_toky, lat_toky = 35.6, 139.6
  lon_cair, lat_cair = 30.0, 31.2
  
  plt.plot([lon_dehl, lon_beij], [lat_dehl, lat_beij],
       linewidth=2,
           linestyle='solid',
           solid_capstyle='round',
           color='#cb2c31',
          marker='o', 
           markersize=6,
           markeredgewidth=None, 
           markeredgecolor='#cb2c31',
       transform=ccrs.PlateCarree(),
          )
  </code></pre>
