get_time_series with source google shopping and keyword birkenstock is the call behind the chart: 261 weekly points from 2021-09-04 through 2026-08-29, stored as {date, value} with no smoothing. get_growth on the same pair, windows 7D and 30D, is the headline math: 88 to 88 (0.0%) and 30 to 88 (+193.33%).
