Bug in Ex_12_03.js 29,740 Cities Code

Not sure if this is a bug in the code, or if it is how the current version of P5.js is working. Took me awhile to get the 29,740 Ciites code to work. I put a push() after line 14 and a pop() after line 22. Here is the code that works...

var cities;

function preload() {
cities = loadTable("cities.csv", "header");
}

function setup() {
createCanvas(480, 240);
fill(255, 150);
noStroke();
}

function draw() {
background(0);
push();
var xoffset = map(mouseX, 0, width, -width*3, -width);
translate(xoffset, -600);
scale(10);
for (var i = 0; i < cities.getRowCount(); i++) {
var latitude = cities.getNum(i, "lat");
var longitude = cities.getNum(i, "lng");
setXY(latitude, longitude);
}
pop();
}

function setXY(lat, lng) {
var x = map(lng, -180, 180, 0, width);
var y = map(lat, 90, -90, 0, height);
ellipse(x, y, 0.25, 0.25);
}

Data examples issue

In a film JSON example 12.5 in a for loops you're trying to find length of film variable which is objects with film.length method, and because of that whole script it's not working. To make example work the length of film object should be found by using this method: Object.keys(film).length

And another issue is in the example 12.4. Script is not working until you specify which element of film object you wanna print i.e. instead of var title = film.title; it should be ... = film[0].title;

and to print information about all the films there should be a loop

Couldn't find cities.csv

where is it?
