Improper scoping in projections?

[lmommaerts]

I'm trying to use the geoAlbersUsa projection, but this code returns an error.

Code:

import { geoAlbersUsa } from 'd3-geo';

const projection = geoAlbersUsa()
const coords = projection([37, -96]) || [];

Error:
d3-geo.js:2216 Uncaught TypeError: Cannot read property 'stream' of undefined

which is pointing to this line: https://github.com/d3/d3-geo/blob/master/src/projection/index.js#L13
and this file: https://github.com/d3/d3-geo/blob/a36f5cac465003ba8b6ceeee3834b1cef2b3a5f5/src/transform.js

I believe (though I could very well be using this incorrectly) that there's an issue with the function scoping, leading this to be undefined.

This is a bug. I will fix it.

Although assuming you are trying to project a point along the Kansas-Oklahoma border, you’ll want to say [-96, 37] because the order is [longitude, latitude].

Fixed in 0.0.4.

Great, thanks!
