Normalization
Each non-empty line is trimmed. Matching is case-insensitive, so Apple and apple are the same comparison key; displayed text keeps the first spelling encountered.
Duplicates
Repeated lines count once in each set. The diagram represents set membership, not row frequency. Each region displays at most eight values; status counts include all values.
