Hello, I just wanted to know that Zeppelin Server (localhost:8080) refers to which directory inside 'incubator-zeppelin' directory. For example, inside any directory(in general), we can run 'python -m SimpleHTTPServer 8000' to run simple http server and the server (localhost:8000) is set up for that directory. So for d3 code, we can write code like
d3.json('data.json', function(.... to get the data which requires the 'data.json' file to be present in that directory for which the server was set up. Thanks, Anish.
