Wave 4 · Phase 4 · Spec §9.1, §9.3, §9.4 · Decision D10 · Answers Q9 (airports), Q7 (prices) · Data airports.json, prices.json

Goal

Who wins the airport trip at JFK, LaGuardia and Newark, at what fare and when; and what riders pay per mile and per minute, and where pricing is most volatile.

Owns

• site/src/airports.md, site/src/prices.md

Starts when

• L05 is done. Build on make site-mock data; switch to real data once L11 publishes

Tasks

• Airports: tiles for trips per day, yellow-cab share, fare to Manhattan (mean or median as D10 settles) and busiest hour; bars per airport stacked to 100% by mode, split by direction; hour-of-day pattern; fares by mode
• Prices: tiles for median fare per mile, price volatility, and cheapest and dearest hour; fare-per-mile strip or box by mode; volatility map (p90 ÷ p10 by zone); fare per minute; borough view

Page rules (all page lanes)

• Every chart has a finding subtitle, units on its axes, and the caption Source: NYC TLC trip records, {as_of_month}
• No pies, 3D, dual axes or “Average” line labels; no logos; keep the footer
• Language: “estimated effect”, “per hour with a passenger”, taxi tips “card-only”
• Check light, dark and 375 px before hand-off

Done when

• Both routes build on mock and on real data; tile labels say mean or median correctly
