We need to find or build from scratch a tool, that will collect users' feedback on graphs they look at. Scientists commenting some obtained distributions is a typical example. Generally speaking, this should be some kind of collective discussion layer for d3js
I guess, that this idea is not new, and I even saw kind of prototype a couple of years ago. Can anyone point to possible existing solutions or maybe frameworks that might be helpful?
Simplest use case - Bob sees d3js scatterplot and observes the strange outlier A on the upper left corner. He clicks on it and writes a comment - 'Was all conditions normal for this observation?'. When John enters the system and clicks on A, he can read the comment and reply smth like 'That's just my cat who ran over keyboard'.
This logic can have lots of extensions, so it's better to use an existing tool.
For those interested, I finally found what I've been looking for -
This is the concept - http://courses.cs.washington.edu/courses/cse512/14wi/lectures/CSE512-Collaboration.pdf and here is prototype - sense.us
