Expected Behavior

Able to import a generated threat model into threat composer.

Current Behavior

Reproduction Steps

Add a few components, import the generated threat-model.tc.json file into threat composer.

Is this a bug in PDK or Threat composer?

[cogwirrel]

Kind of both, I've raised one for threat composer here: awslabs/threat-composer#100

I think we should keep this open so we remember to switch to svg output.
