Given the following dataset:


PartID    SupplierID    PartName    PartCategory    PartQualityScore

A1    S1    Bolt    Hardware    8

B2    S2    Nut    Hardware    7

A1    S1    Bolt    Hardware    8

C3    S3    Screw    Hardware    9

A1    S1    Bolt    Hardware    8


If you configure the Value Count node to count the unique values in the PartID and PartCategory columns, the output would look like this:


Column Name    Value    Frequency

PartID    A1    3

PartID    B2    1

PartID    C3    1

PartCategory    Hardware    5
