ok here is a concrete example. I am still trying to connect the dots..If I were to split Zeppelin as both front end and backend then I wouldn't choose to use Zeppelin in the first place. The main motivation for me to explore Zeppelin is that I don't have to spend time developing different visualiztions. I have used tableau before I see Zeppelin to be similar in some ways. ok now here is the problem I am trying to solve and any help I can get will be great!
say I am trying to build a time series graph(bar graph or whatever works) where my x axis represent time and y axis represent total number of transactions and say every second I get updates through web socket from my server and I need the graph to be updated every second. thats it. please let me know if that is feasible.
