d3.jsonp

Demo: http://bl.ocks.org/4494715

A plugin for supporting the JSONP technique of requesting cross-domain JSON data. This plugin is unstable and in development.

Whenever possible, use CORS instead of JSONP. CORS handles errors properly, has better security, and supports formats besides JSON. See enable-cors.org for more information.

// autogenerate a callback in the form d3.jsonp.foo
d3.jsonp('foo.jsonp?callback={callback}', function() {
  console.log(arguments);
});

// specify a callback
d3.jsonp('foo.jsonp?callback=d3.jsonp.foo', function() {
  console.log(arguments);
});

This plugin requires servers to accept callbacks with numeric and . characters. Unlike d3.xhr functions, there is no error handling.
