Using Categorical Schemes for non-categorical data results in unhelpful error

See original GitHub issue

When I tried to supply scheme=‘dark2’ for a qualitative column I got

Javascript Error: e is undefined

Looks like there’s an error in an exception handler somewhere

i.e.

color=alt.Color('Loss', scale=alt.Scale(scheme='dark2'))

Fails (reasonably) since ‘dark2’ isn’t a continuous scale, but the message could be more informative.

color=alt.Color('Loss', scale=alt.Scale(scheme='viridis'))

is ok.
