Q - How is D3 different from user interaction manipulating DOM elements?

A - the DOM is manipulated by data

Q - how do I add D3 to my app?

A - minified file, CDN, unminified (we did <script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script> in class)

Q - Assuming a model and controller exist, where would I write a custom helper method that is available application wide?

Ruby sees everything, from simple values (strings, integers), to complex data structures (arrays), as [Question 2]

Ruby is a [QUESTION 1] based, object oriented language. Every [Question 2] is an instance of a [QUESTION 1].

Ruby objects are most often handled via [Question 3] that represent them.

Every object is capable of understanding a certain set of messages.

These messages correspond directly to a [Question 4] - a named executable routine, whose execution the object has the ability to trigger.

	<!DOCTYPE html>
	<html ng-app="toyStore">
	<head>
	<link rel="stylesheet" type="text/css" href="bootstrap.min.css" />
	<script type="text/javascript" src="angular.min.js"></script>
	<script type="text/javascript" src="app.js"></script>

	Consider this code being found in the controller:

	$scope.stuff = ["a", "b", "c", "d"];
	$scope.changeIt = function(idx) {
	$scope.stuff[idx] = "x";
	};

	And this unordered list on the page:

	<ul>

	class Car
	attr_accessor :color

	def speed
	speeda = 100;
	end

	def print_speed
	puts @speeda
	end


	Object identity
	expect(actual).to be(expected) # passes if actual.equal?(expected)

	Object equivalence
	expect(actual).to eq(expected) # passes if actual == expected

	Comparisons
	expect(actual).to be > expected
	expect(actual).to be >= expected

	Ruby is a CLASS based, OBJECT oriented language. Every _______ is an instance of a _______.

	Ruby sees everything, from simple values (strings, integers), to complex data structures (arrays), as _________.

	Ruby OBJECTS are most often handled via ________ that represent them.

	Every OBJECT is capable of understanding a certain set of MESSAGES.

	These MESSAGES correspond directly to a _________ - a named, executable routine, whose execution the object has the ability to trigger.

	Wire brush to get off the big dirt
	Brush with softer brush to get the rest ofthe dust out
