What would you expect from this analysis as output? A new polygon geometry or a column with categories?

confirmed with @andrewxhill, a new column with the cluster number (or something like that)
from camshaft.
Inputs:
- Many points in a table
- N, input of desired clusters
Output
- N point geometries (centers of clusters)
- N cluster IDs
from camshaft.
what is the ETA?

Should have a crankshaft and camshaft PR ready today

ok, nice
from camshaft.
Sorry.. talking with stuart my answer is actually wrong for the kmeans bit
Inputs:
Many points in a table
N, input of desired clusters
Output
Many points table
Column of 1-N cluster IDs
So a table with 100 points will return a table with 100 points plus a cluster id column
from camshaft.
We also have another helper function that will take those clusters and produce the weighted centers of those N clusters based on some other column
Video of the process is here :

This should be in place on both the crankshaft and camshaft sides
from camshaft.
