[Feature Request] Debugger Dashboard string tensor visualization support

[MtDersvan]

Right now all string tensors are visualized as NaN symbols on a 2D plot given correct dimensions:

Would it be a good idea, to visualize them as a step-value dict or a list? Or even as a tensorboard:6006/#text format for text?
Thanks.

It is more likely that this will be fixed in the debugger_v2 plugin than here.
