Project for the Data Visualisation course at the University of Edinburgh.

In this interactive visualisation project, we present the relationship between the current COVID-19 outbreak and the air pollution levels in Europe. Since the outbreak, many European countries have gone into a lockdown with varying levels of severity, impacting both traffic and industry. Thus, the choice has been made to make a visualisation that shows if and where air pollution levels have changed in Europe since the first cases arose.

On the map we plot the air pollution data (NO₂) of 29 European countries from the day the first COVID-19 confirmed cases appeared (24 January 2020) until the recently updated date (5 April 2020). We also plot the confirmed cases of COVID-19 for all countries per day and the average NO₂ level of pullution on the right panel.

The visualisation can be accessed here: https://datavis-project.herokuapp.com/

We first collected the NO₂ air pollution data from https://www.eea.europa.eu/themes/air/air-quality-and-covid19/monitoring-covid-19-impacts-on from the beginning of 2020 until now and filtered out the days initial days of January for which there were still no confirmed COVID-19 cases in Europe. We then collected the COVID-19 data from https://github.com/CSSEGISandData/COVID-19 and preprocessed both datasets into JSON objects

The webpage was created using the React.js library. For the map we used the Google Maps JavaScript API and for the charts we used react-chartjs-2, which is a wrapper for Chart.js
