732 current US openings mention Parquet — rank 2 of 6 in format.
Roles mentioning Parquet that were actually open on each of the last 2 days: 48 on 2026-09-11, 3 on 2026-09-12.
Counted from a daily record of which postings were still listed, so it reflects roles open on each day rather than roles posted. The vertical axis starts at the period low (3) rather than zero, which exaggerates the shape — the two numbers above the chart are the actual values. Days on which the collection did not run a complete pass are excluded rather than drawn as a dip.
