Exercise Three: Looping through data to create a simple bar chart.

We loaded up our Columbia Public Schools JSON in class Tuesday and iterated through the rows using a "for loop." We touched on three main concepts:

1. Loading data via JQuery's super simple ajax method, $.getJSON:

$.getJSON("js/filename.json", function(data) {
	doSomething(data);
})

2. Passed the data between functions. (See Paramaters and Arguments)

3. We looped through our data, and appended some markup to the page to create a simple bar chart. Some references you might find useful:

• For loops
• Variables
• Operators
