Coronavirus visualization.

I got tired of sites with Ads or sites with poor data visualization. Hence a new one.

This uses the NYTimes Corona-19 Virus data. An initial dataset take from that repo is located in src/models/data.

TODO: Make it update periodically.

Testing is done using mocha, which is invoked using npm:

$ npm run test
