Clarify documentation

[lapidus]

I am trying to run the ddfCsvReader on the server per the documentation:

const Vizabi = require('vizabi');
const ddfCsvReader = require('vizabi-ddfcsv-reader');
const readerObject = ddfCsvReader.getDDFCsvReaderObject();
Vizabi.Reader.extend('ddf-csv-reader', readerObject);

This gives me "d3 not found". So I simplify to:

const ddfCsvReader = require('vizabi-ddfcsv-reader');
const readerObject = ddfCsvReader.getDDFCsvReaderObject();

This works after building node_modules/vizabi-ddfcsv-reader.
(Note: The build works but gives some errors "ERROR in Entry module not found: Error: Can't resolve './src'")

Would be super helpful if you could update the example and the built version.

Thank you :)

Ah right, yes, Vizabi requires d3 (we didn't include it in the build), so not requiring removes the need for d3.

@buchslava there were changes to the API to worker with WS right? Does documentation need updating now?
