VAAS (visualization as a service) is ready to play with now

After some thoughts around how to advance Columns as a smart visualization platform, I eventually open-sourced its core data model and graph model here https://github.com/varchar-io/vaas

Along with it, we have made it ready to play with, a few lines of code will produce a flexible story with full capability for customization. I wish this is something many developers will find interesting and useful.

We also created a landing page for this Open Source repo at https://columns.ai/dev, check it out and share your feedback, please!
