解决方案

The modern browsers now have good support for base64 encoding and decoding. There are two functions respectively for decoding and encoding base64 strings:

• atob() decodes a string of base-64 data
• btoa() creates a base-64 encoded ASCII string from a "string" of binary data

This let's you create data uri's easily i.e

var longText = "Lorem ipsum....";
var dataUri = "data:text/plain;base64," + btoa(longText);
//a sample api expecting an uri
d3.csv(dataUri, function(parsed){

});
