3D Cat DataΒΆ
This example generates a Mapper built from a point-cloud sampled from a 3D model of a cat.

..Composing projection pipeline of length 1:
Projections: sum
Distance matrices: False
Scalers: MinMaxScaler()
..Projecting on data shaped (7207, 3)
..Projecting data using: sum
..Scaling with: MinMaxScaler()
Mapping on data shaped (7207, 3) using lens shaped (7207, 1)
Minimal points in hypercube before clustering: 5
Creating 15 hypercubes.
