Parallel Sets
Categorical flow: Sankey for nominal data, lane by lane.

Parallel Sets visualize categorical co-occurrence across several dimensions as flowing ribbons between parallel category bars. The categorical sibling of parallel coordinates.
N parallel category columns, with width-weighted ribbons between adjacent columns showing co-membership.
When every dimension is categorical, scatter and parallel coordinates don’t apply. Parallel sets do.
Three ways teams use it.
Demographic × answer × segment.
Source × device × purchase outcome.
Department × role × tenure bucket.
