During the beginning of the pandemic, I was interested if vaccination would affect COVID-19 cases. I implemented a Python Script that generates a graph plotting total vaccine doses per 100k population versus cumulative COVID-19 cases per 100k population in last 7 days for each of the 50 US states. Each time the Python script is run, it looks for updated data from the CDC. A trendline is plotted as well.
