List virtualportgroups in a cluster count VMs and VMhosts

Get-Datacenter "CG-SO" | Get-Cluster|Get-VMHost |Get-VirtualPortGroup tells me the virtualportgroups and vlans.

I can get host and vm counts with the following:

Get-Cluster | Select Name, @{N="Host Count"; E={($_ | Get-VMHost).Count}},  @{N="VM Count"; E={($_ | Get-VM).Count}}

How do I combine the two to get the following?

Cluster                                         VirtualPortGroup          Vlan   VMhost Count   VM Count

I want to identify those virtual port groups no longer in use to evaluate if they need to be removed. We've had several vlans removed from our network infrastructure over the years.
