Could you explain more concretely what kind of "support" you have in mind? A graphing library isn't like Pydantic, you aren't supplying typing information from your own code to it as part of the API. Do you just mean that it should provide type annotations in its own interface? Because I do see .pyi typing stubs in the distribution.

We do provide some type hinting but it is more a recent development as we are building on the legacy code from proplot which did not provide any. I am in favor of using typing more.
