Coronavirus Data Plotter

========================



*COVID-19 / Coronavirus interactive, customizable data visualization and

animation portal. Together, we can make it through this.*



Source repository for , the Coronavirus Data

Plotter.



From the front page:



>   On this data portal, explore different aspects of COVID-19 /

>   Coronavirus time evolution. I put this together because I saw a lot of

>   different visualizations and data views over many different sites but

>   no way to explore them all within the same tool. I hope this will be

>   as helpful for you as it was for me, in helping process and understand

>   the torrent of information and numbers we see in the news and on our

>   phones every day.

Code Background

---------------



The overall infrastructure is built in *yarn* scripts.  This is actually my

first ever full javascript-based project, so admittedly I'm not too familiar

with the ecosystem.



This project also served as a learning project for me for [Purescript][]

(programming language), [Halogen][] (UI framework), and [D3.js][] (interactive

visualizations), so a lot of the actual code itself may not be exactly

idiomatic.  My programming background is a Haskell tradition where I heavily

use [dependent types][] to ensure type safety and correctness and help guide my

implementation and make things more smooth during the development and

maintenance process...though I admit that using a off-mainstream code

discipline/style that is not exactly idiomatic within the already

not-very-common language I am using makes the barrier for contribution pretty

high.  However, I am definitely willing to help explain any aspects of the

implementation if you have any questions.
