This is incredibly useful, a lot of my peers will certainly love it for quick prototyping data manipulation and exploration. I know I will. This is a very clever/usable implementation of flow-based programming (FBP), which is dear to many people's heart in HN and out. FBP matches very easily the mental model of data flow and calls for quick mouse- or touch-based manipulation. Coming up with a usable UX for such paradigm is not trivial though, and your project seems on a good track. I can only encourage you to take the (harsh) criticism in this comments' section with the necessary distance, and keep working on the project, because it's very good! Well done!
