title: How to achieve this using HighCharts Network chart
body: <p>We are trying to use the network chart in HighCharts to show two sets of nodes connected to a central node, as though they were two separate groups. How can we achieve this? We have tried the API but it didn't get us too far</p>
  <p>Any guidance is much appreciated.</p>
