Missing method?

[ChrisBAshton]

Apologies in advance if I've misunderstood something or logged this issue in the wrong place!

I've built numerous pan-and-zoom maps before, all of which used either the mercator or albers projections (I should also point out at this point that I'm using v3, not v4, of d3): https://github.com/d3/d3-3.x-api-reference/blob/master/Geo-Projections.md

I'm now trying to build a US map, and switched to the albersUsa projection. All of a sudden, my map code is giving me lots of errors, and it suggests that there is a missing method in the albersUsa projection?

this.projection = d3.geo.albers() // `albers` is ok, `albersUsa` is not!
            .scale(this.mapModel.get('mapScale'))
            .translate(this.mapModel.get('translate'));

// ...a while later:

let bounds = [0,0]; // just for this example
const coords = this.projection(bounds);

In the albers projection, coords comes out as [2065.4195284613525, 73.63503703113963]. But if I switch to albersUsa, coords comes out as null.

Any advice would be much appreciated! Thanks

As a fixed composite projection, d3.geoAlbersUsa does not support the following projection methods: projection.center, projection.rotate, projection.clipAngle, projection.clipExtent.
