Exploring Covid19 datasets

April 10, 2020

Since there was a lot of misinformation being spread relating to COVID19 I decided that I wanted to visualise some of the data available.

I was keen to do this as I wanted to keep an eye on what was happening around me. I was also keen to see if I could compare datasets to try and produce some visualisations to disprove some of the more extreme view points relating to the outbreak, like 5G causing the outbreak etc.

ObservableHQ and covid19api.com

Being my first time using ObservableHQ, I decided to start simple, so that I could get to know the platform and what was possible. I started out by creating a ObservableHQ notebook consuming the covid19api.com JSON API and created a simple graph in Vega Lite.

You can view this notebook here: https://observablehq.com/d/ed92b04582f8b2e6

Covid19 API Graph

What I learnt:

  • For the most part ObservableHQ notebooks are just like writing pure JavaScript
  • Vega Lite
  • covid19api.com was not accurate enough in all cases

I decided this exploration that I would need to use another dataset but that ObservableHQ is a very handy platform.
