In fact, I updated the data frame package to be able to read the CSV file
directly, without having to process it, so the example now becomes:
#lang racket
(require data-frame)
(define df (df-read/csv "worldcities.csv" #:quoted-numbers? #t))
(define ((is-city? name) v)
(equal? (vector-ref v
That database is simple enough to use directly, not sure if it needs a
separate package:
#lang racket
(require data-frame)
;; The worldcities.csv file has all values quoted, so df-read/csv reads them
;; all as strings. Convert a series to numbers.
(define (->numeric df series)
There's a small free database here too:
https://simplemaps.com/data/world-cities
I started writing a simple query system for it this morning (csv->rktd,
then just list of assoc operations).
