API Method `hclplot()` from Original R Package Missing?

[avanavana]

Though the documentation for the original R package says of this python port:

For Python users a beta re-implementation of the full colorspace package in Python 2/Python 3 is also available

I cannot seem to use the hclplot() function, and searching the codebase here turns up nothing for it either.

Am I missing something? Is it here under some other alias, or is it just missing from this port?
