Can't get clusters

[yahyazini]

Hey guys, first of all thanks a lot for this awesome library that really helps leverage the complexity of D3 for someone who is not a DataScientist (like me).

My issue is that I can't get the clusters using the: var clusters = alchemy.get.clusters();
And I get the following console error:
Cannot read property 'clusterMap' of undefined

I'm trying to create hulls around the clusters like this:

Any help is appreciated

Thanks a lot

As per #472, I'd love clusters to work properly.

I'd be prepared to pay a reasonable hourly rate for a fix, if anyone here is into that?
