Don Meltz - AICPIs this a case for projections in GeoJSON? Or is it a case against using ArcGIS Online?
Chris McClain@DonMeltz its an infographic why does it need a projection?
@ChrisMcClain
As an infographic, it doesn't. But if you want to join your GeoAnalysis output into it through your GIS of choice, then it makes sense to try to keep it visually correct with uniform hexagons.
And if you want to display the infographic in an embedded map as an overlay for some reason, it needs a spatial reference.
Output as a jpeg added to a Word doc, then no, no projection needed.

@DonMeltz Then you just need to ensure you create it in the intended projection because any change is going to warp it in some way. AGOL will support any projection, but if you want to use their base maps you are stuck with web mercator.

Yes. That's my point. The GeoJSON format specification says "WGS84 only". And AGOL maps say "Web Mercator only", with no on-the-fly reprojection.
This conflict would apply to any GeoJSON layer, not just my Hex States.
