The Trends MCP calls for this keyword
get_time_series with source google search and keyword iphone 18 is the call behind the chart, returning 261 weekly points from 2021-09-25 through 2026-09-19 stored as {date, value} with no smoothing, which is the only series this page is allowed to quote. get_growth on the same pair, windows 7D and 30D, is the headline math: 100 to 62 (-38.0%) and 21 to 62 (+195.24%). Mixing the YouTube 64 with the Google Search 62 would invent a dual-source story the stored JSON does not tell.
