It took me a few weeks, one of them was fully on this project. Most of the time was spent on investigating and improving the different canvas implementations (map and charts work on an html5 canvas abstraction). A lot of the time was spent on false directions but this is expected. One particular direction was reusing Web js libs to do the charting logic but it turned that it is easy enough to implement on my own.

In my day job I author web dashboards (working in HP on performance testing tools) so I thought it would be cool to have those dashboards directly in the terminal. But I would have done it even without this incentive. I do a lot of projects just because they inspire me, check out GifW00t! https://github.com/yaronn/GifW00t
