I am looking for an online data visualization (plotting, graphing, network analysis etc) platform where I can upload data in csv or text format, and one can interactively visualize the plots. One could also share with others so that they can also manipulate or customize it. I saw google public data is giving somewhat similar solution. Let me know if you are aware of anything more advanced using d3 javascript or other libraries.
Do you want to write your own software or to analyze your data?
