How to load data using XHR in D3
I am experimenting with D3 on my localhost. I would like to load data to
be visualized from an external source on the Internet.
I am looking for instruction/examples of how to how to load data using XHR
in D3 (there is documentation here, but it does not suffice for me, I am
looking for code snippets https://github.com/mbostock/d3/wiki/Requests)
I have tried the following and it does not work for me:
d3.xhr("http://example.org/json-test.json", function(data){
alert(data); //no data is returned
});
Thanks
d3.json( url, function( error, data ) {
ReplyDeleteif ( error ) alert('loading failed');
alert(data);
} );
Callback arguments:
1 - error if any or null
2 - data if any
d3.xhr( '/audio/mp3' )
ReplyDelete.responseType('arraybuffer')
.get( function( error, data ) {
if ( error ) alert('error');
loaded_array_buffer = data.response;
} );
