Nice, this looks pretty similar to Quantrix Modeler and Javelin, it's precursor. Sadly Javelin suffered from MS's shenanigans with Excel bundling. I was wondering when someone would reimplement those two on the modern web stack. Before the web became popular for these types of apps I had prototyped something similar using pandas and PyQt.

> Before the web became popular for these types of apps I had prototyped something similar using pandas and PyQt. Haven't you open-sourced your prototypes? A hackable desktop app made with PyQt and exposing Pandas functionality a nice GUI way seems a way more appealing to me than yet another heavy web application thet depends on a 3-rd party server and requires an Internet connection to use.

  That's a really good question. I generally end up building these tools for personal use or to see if some design space is worth exploring, and so don't bother cleaning up the code/making it easy for other people to run. In addition, people now have the expectation that people releasing open source code owe them some manner of improvements/support/maintenance, something I'm not interested in doing. I like David Beazley's recent tweet about releasing his code asis - https://twitter.com/dabeaz/status/1069236767029633024 https://twitter.com/dabeaz/status/1069236767029633024 I've got a number of tools like this - a basic SQL GUI for doing analytics (https://news.ycombinator.com/item?id=14050833 https://news.ycombinator.com/item?id=14050833), a Tableau like clone with interactive graphics for visual analytics (https://pbs.twimg.com/media/Cyji3jRWIAA2LRY.jpg:large https://pbs.twimg.com/media/Cyji3jRWIAA2LRY.jpg:large) - your comment is making me reconsider that people might find them useful without any expectation of support/warrantee of fitness.
