Simplest approach would be to push the streaming data (after the
computations) to a SQL-Like DB and then let your visualization piece pull
it from the DB. Another approach would be to make your visualization piece
a web-socket (If you are using D3JS etc) and then from your streaming
application you can push the data to the web-socket which will power the
