Separate bandwidth in x and y directions? + NRD formula

3

As discussed over at [the Observable forum](https://talk.observablehq.com/t/density-contours-change-dramatically-based-on-size-aspect/794), it might be nice for the bandwidth to accept a 2-entry list or an object with `x` and `y` attributes or the like,...

d3.geoBounds gives incorrect bounds for one of the polygons in world-atlas countries50, Fiji)

1

If I do: ```js const countries50 = (() => { const url = "https://cdn.jsdelivr.net/npm/world-atlas@2/countries-50m.json", raw = await fetch(url), topo = await raw.json(); return topojson.feature(topo, topo.objects.countries); })(); const fiji = countries50.features[170];...

forwardRotationLambda does not normalize angles beyond ±3π

7

If you try to project angles outside the range [–3π, 3π], it can result in wonky artifacts from resampling: Here is the current code for `forwardRotationLambda` https://github.com/d3/d3-geo/blob/v3.0.1/src/rotation.js#L17-L21 ```js function forwardRotationLambda(deltaLambda)...

Negative spaces in Safari appear outside subscript that uses them

I expected `mkern` and `mskip` commands to only affect the spacing at a single place, but they seem to cause follow-on spacing bugs afterward. An example can be seen by...

Netz, "Counter Culture"

I recently enjoyed reading this paper by Netz (2002) about the Ancient Greek use of counters as a tool of thought: http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?db_key=AST&bibcode=2002HisSc..40..321N&letter=.&classic=YES&defaultprint=YES&whole_paper=YES&page=321&epage=321&send=Send+PDF&filetype=.pdf https://scholar.google.com/scholar?cluster=860996077996231654

consider using Eriksson’s formula in preference to L’Huilier’s for the area of a spherical triangle

17

[Currently S2 calculates](https://github.com/google/s2geometry/blob/master/src/s2/s2measures.cc#L56-L110) the signed area *E* of an oriented spherical triangle with vertices at unit vectors [*a*, *b*, *c*] by first finding the measures of the central angles between...

some way to save/reload scmaps

3

In Matlab it’s possible to save any arbitrary Matlab variable to a file, but apparently for classes, unless extra work is done by the class (in the saveobj/loadobj methods), the...

Some more convenient way to dispatch events?

3

I am getting tired of writing (optionally with `CustomEvent` instead of `Event`): ```javascript viewof foo.dispatchEvent(new Event('input', {bubbles: true})); ``` It takes a while to type, requires 9 different non-alphabetical characters,...

Many table views in GUI software (e.g. file managers, spreadsheets) allow viewers to resize columns by dragging left/right from a target in between column headers, reorder columns by dragging a...
