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 databtoa()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){
});
