[BUG] Extension listed as view plugin for CKAN v2.10 but it does not seem compatible

[tazchalmers]

Describe the bug
I understand it's only documented as supported in CKAN 2.9, but as CKAN has it in their list of View plugins for v2.10 are there plans to make it compatible with CKAN 2.10+?

In CKAN v2.10.4 (dockerised) there are lots of formatting issues and even though the cursor changes to a hand when hovering over the pills, it is not possible to drag them. Underneath on a giant image, overlayed text says: "The requested graph type combination is currently not supported. Please try with another pill combination." I tried with a very simple 2 numbered column csv amongst other csv/files.

ckanext-visualize version affected
v1.0.0 - there is only one.

Expected behaviour
Something like the documented screenshots.

Logs
