L14 · Pages: Zones

Wave 4 · Phase 4 · Spec §9.1, §9.2 · Decision D13 · Answers Q1, Q8, Q10 · Data zones/index.json, zones/{zone}.json, taxi_zones.geojson

Goal

263 zone pages from one template, plus the /zones index with the city-wide maps (if D13 is agreed).

Owns

• site/src/zones/[zone].md, site/src/zones/index.md

Starts when

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

Tasks

• Zone page: tiles for trips per day, ride-hail share, median and 90th-percentile wait, top destination; share trend; 24 × 7 heatmap by mode; waits; top destinations linking to their zone pages
• Thin zones (islands, very few trips): null percentiles and short series show a clear “too few trips” state
• Index: level map (ride-hail share, sequential blues) and change map (share change vs a year earlier, diverging, centred on 0); a searchable table linking to zone pages; a Q10 view of where yellow cabs still win
• Zones 264 and 265 never get pages
• Check build time and output size for all 263 pages

Page rules (all page lanes)

• Numbers, titles and subtitles come only from JSON; no digits in markdown prose
• Use components from site/src/components/ only. Need a change? Add a Blocked note for the integrator
• 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

• All 264 routes build (263 zones + the index); every zone file is under 50 KB and every route within budget
