Upgrade d3 geo projections #5112

archmoj · 2020-09-01T03:34:40Z

Replace old d3.geo functions with upgraded d3-geo modules (that support IE) as part of d3 bump cc: #424.
Some new geo projections e.g. satelite could potentially be added as listed in 8dd4ba0 to address #4781.

This would also result in reducing the size of various partial bundles that do not need geo trace.

This looks like a good idea, but I think we need to be more careful about each projection we add: (1) does it work well in the simple case? In your demo codepen a number of them fall look pretty bad either immediately or easily as you zoom / pan around so should probably not be included without some adjustment. (2) maybe you've already done this, do they support all the same parameters as the existing ones? isConic? lonaxisSpan / lataxisSpan? Any other special cases? (3) each one we add needs to be included in at least one mock, maybe more so we can ensure their parameters work right. geo_fitbounds-locations says it includes "all projection types", let's ensure that stays true.

- note upgrading to latest versions is not possible atm - due to ES2015 syntax and drop of IE support

Thanks for the notes @alexcjohnson.
With the updates (reflected in the PR description now) no new projections were added in the API as a result of this PR.

Why did these 2 tests get removed?

If I recall (as mentioned in the commit message) there used to be a bug in d3.geo where a function returned NaN positions. And we guarded against it.

But these tests are just using the high-level API, not d3 geo itself. If they started failing, that means something changed about the user-facing behavior. What changed? Are we comfortable with that change? I'd much prefer if we can adapt the tests to the new version so we can see the difference.

Good question. Pointing to the fact that rebase somehow forgot to remove geo/projections.
It is now fixed in 557ebde.

This test should still be able to pass though. Perhaps the exact pixel positions need to change because there's some small change in how the projection is applied? If I try to manually follow what's going on in the test (I believe it's hovering on the point off the coast of Africa, then slowly mousing off the edge of the globe) the behavior looks identical before/after the change. So we should be able to bring the test back, but if the exact values need to change a little (px = 390, py = 290 and if(px < 402) that's fine.

Good call. Adjusted in 647b0dc.
In fact with previous positions the tests didn't pass locally. But now the test now passes both locally and on the CI.

We don't strictly speaking need to merge this PR for v2, so let's leave it alone for now?

That's what we may end up doing. But it is worth having the conversion going before committing to v2 IMHO.
