Include income groups in regions.json

[marcelgerber]

Core problem

We would like to have income groups as part of "your local entities" in the redesigned entity selector.

To do this, we would want to have these income groups in our regions.json file, and in the detect-country CF worker.

Proposed solution

Our own regions.json are being taken from ETL, and in particular from the ouput of ETL step grapher/regions/latest.

It would make sense to bundle the latest wb/.../income_groups steps into that, too, and to create additional rows that look something like OWID_INC_H,High-income countries,High-income-countries,aggregate, [...], USA;DEU;FRA;[...] to the regions.csv file.

Note that this would also entail assigning OWID entity codes to these income groups, which I think makes sense. But I'm not married to the OWID_INC_... scheme, we could also go with OWID_WB_HIC or something similar.

Alternatives

An alternative would be to create another grapher/latest/ step for income groups; something like grapher/latest/income_groups.

Context

There's a Slack discussion on the entity selector feature, and one on the proposed update of the regions dataset.

@marcelgerber what is the status of this work? Is the PR still relevant and will be merged? Is that work on hold unti the end of the cycle?

Hi Daniel!
The current status is that the remaining work for this (which consists mostly of providing a nice tooltip with more information) will take a few more hours, and so I've deferred it for after the multiD project.

The work on the etl side and on the cloudflare-workers side has already been completed and is ready for primetime.

I should also mention that there has been some further discussion on Slack about this between Ed and Pablo R, but I think the outcome of that discussion was basically that we should be good to go ahead.

Ah, and one more thing, I'm not entirely sure how/if the tooltip here could be related to Region DoDs (#3333)? If our custom tooltip mostly just links to the definition of an income group, then Region DoDs could do that too.

Cool, sounds good! I just chatted with Sophia about the Region DoDs and we think it makes sense to finish both of these features separately and then consider adding a special case for the intersection.
