Cannot read property 'center' of undefined

[elsehow]

When I load in some data I constructed (gist), I get an error.

gio.min.js:2 Uncaught TypeError: Cannot read property 'center' of undefined
    at C (gio.min.js:2)
    at gio.min.js:2
    at Object.v [as createGeometry] (gio.min.js:2)
    at P.processDetail (gio.min.js:4)

    at V.a.process (gio.min.js:4)
    at l.a.process (gio.min.js:4)
    at o (gio.min.js:2)

My strong suspicion is that one or more of the Alpha2 codes I passed in is unrecognized. But this error message doesn't tell me which one.

Does anyone happen to know what this error message tends to mean in giojs?

I hackily resolved my problem by taking the sample data in examples/data/sampleData.json and doing a set difference with the ISO Alpha2 codes in that file vs the ISO Alpha2 codes in mine.

The unsupported Alpha2s were:

{'CC', 'EU', 'HK', 'MO', 'SX'}

My suggestion: When an Alpha2 isn't recognized, throw an error like:

Alpha2 code 'EU' not found in map.
