The tool is a web application that display COVID-19 data by country from December 31, 2019, namely the number of cases, deaths, cases per million, and deaths per millions. It allows users to view the data on a timeline, click on data points to learn more about a country’s status, and zoom into certain regions (both by name and by latitude and longitude). This project was submitted to the TecHacks 2020 hackathon created over a weekend.

Technologies Used

This project was built using:

  • Cesium/Resium: Resium is the React component library for Cesium.
  • React: The frontend of this project is done entirely in React.
  • Bulma: The CSS framework.
  • czml-writer: The data format I used was czml.
  • Google Sheets’ geocode function to turn countries into latitude and longitude.
  • And finally, last but not least, dataset from Our World in Data.

This looks awesome, thanks for sharing this!

I particularly love watching the timeline and switching to 2D mode to see the whole world at once, and how it starts spreading slowly but at some point it’s just everywhere.

This is really nice! I keep speeding through that timeline watching the spread. I love the transparency and colors you used to make these numbers easier to understand.
