JavaScript D3.js Data Binding with D3.js Request Methods

How do I get d3.csv() or d3.json() to work outside of the workspace?

When I try to use d3.csv() or d3.json() with local files, I get an error in the console. "Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource."

Code: 

 d3.csv('climate_data.csv', function(data) {
    debugger;
 });

Or 

 d3.json('phones.json', function(error, data) {
    // do something with the data here
    console.log(error);
    console.log(data);
 });

The files are stored locally.

In order to get these files to work locally you will need to use an HTTP server. Personally I like to use MAMP.

Hope that helps :)
