Counts are Google Places (New) listings from each region's committed crawl data; a place joins a frontier when its listing name or Google type matches that category. The pack build date shown is when the routing pack was compiled — the original crawl collection dates are not recorded, so listing freshness is unknown. Drive times on the map are free-flow estimates — road-class speeds, no traffic, no parking, no queue at the counter — computed only out to a two-hour limit; beyond that a place is simply uncharted. Quality scores are ratings scaled to 100 — a rating-derived proxy, not a taste measurement. Unrated places cannot be charted.

Only places whose Google listing says “Halal Restaurant” or whose name contains “halal”. Cuisine alone is never treated as certification — many halal kitchens are missing here, and listed status is unverified.

The full pipeline — corpus, road graph, speed model, routing and ranking — is documented on the methodology page.
