I've done similar work with R and Shiny which I think is great for communicating models but the R learning curve is sometimes a little steep. Blabr looks like it would be great…

Unclear use cases compared to spreadsheets and programming languages

Not suited to heavy computation
From 2 comments
Thank you very much for a very detailed answer. It is much clearer to me what are the strengths of the project now. Something I wonder is if there are any plans to make blabs…

Dataset import is limited
From 2 comments
Does it support to import big datasets? If so, would the performance of browser hurts?

Is it possible to embed blab? Looks very clean and simple, would be nice to use it as a part of a blog post.

Open source release
From 2 comments
Great approach to a problem. I'd like to see more tools like this. Is it open source? Can I suggest you to support double screen so that the results is always visible?
tigroferoce on HNWhere is the repo? A project here in Santa Fe may be a useful addition and I'd like to get in touch with the authors.

Questions
Can plots be customized, e.g. fill_between
From 1 comment
Is it possible to alter the lines in the plot? For example `pyplot.fill_between` I'm thinking of ipython notebook viewer (now Jupyter[0])which has a cool xkcd[1] plot example.…
