Here’s another take of the inverse operation, replacing array.map with Array.from, and replacing array.reduce with Object.fromEntries: ```js Array.from( d3.group(data, d => d.religion), ([religion, group]) => Object.fromEntries( [["religion", religion]].concat( group.map(d =>...

Another difference is that Array.from accepts values like `{length: 42}` whereas D3 only accepts values that are iterable. (This is why we do an explicit test for the Symbol.iterator method...

Perhaps it’s worth introducing two new methods: one for converting an array of objects to an object of arrays, and another for converting an object of arrays to an array...

I think the \n is fine—that’s not really a DSL (at least not a new one). And in the other case you mentioned, you turn off the repetition filter and...

It would also be nice to have meaningful ribbon widths. For example, if the start and end value are the same, the ribbon width should be constant. I believe this...

I’m leaning towards the names d3.lab (CIELAB), d3.luv (CIELUV), d3.xyz (CIEXYZ), d3.lchab (CIELCh_ab), d3.lchuv (CIELCh_uv), and the corresponding d3.interpolate* methods (though I’m not sure I’ll bother with d3.interpolateXyz, as I’m...

I’m only planning on deprecating, not removing. We could keep d3.lch (non-deprecated) as CIELCh_ab, but the point is that it would be ambiguous and inconsistent if we also have CIELCh_uv...
