It looks like a plain html page but requires JS to view anything except: "Please enable JavaScript to use this site." What a wonderful time to live in.

Anyway, do I get this right: They expect users to be experts in data analysis but not being able to load the data into whatever software they use? They want me to share data and to offload my data into their walled garden that can be accessed only via their service? If I wanted to share my data, wouldn't I rather use something more accessible?
