Why

A few weeks ago, I blogged about mapping NYC COVID-19 data in GeoPandas and Plotly. When I was coding those visualizations, I realized they were great for creating quick maps within the Jupyter Notebook environment, but lacked certain features particular to more complete geospatial renderings. Therefore, I took it upon myself to do a little digging and learn the basics about open sourced, full-fledged professional Geographic Information Systems (GIS) software package QGIS.

What

The following will be a basic tutorial of how to take a shapefile merged with associated attribute data, and import into QGIS to create a complete bivariate graduated symbology map within the QGIS ecosystem. The data will be solely from current NYC COVID-19 data github. This will allow us too compare and contrast population and disease rates by Zip Code Tabulation Area (ZCTA).

How

Goto QGIS.com and download the most up to date software package for your operating system.
