Slicer can do exactly this. The file that you drag-and-drop is a Slicer scene file that contains models, transforms, and OpenIGTLink configuration.

You can build the transform tree from information in the urdf file. To make this very easy, I’ve implemented an automatic importer script. You can download it from here:

The script does not support all possible features (e.g., I’ve only added “revolute” joint types), but can be easily extended as needed.

All you need is to copy-paste the script into Slicer’s Python console in a recent Slicer Preview Release (Slicer-5.7.x; Slicer Stable Release is not compatible, as it does not support selective display of transform rotation handles):
