This is generated by a program that scrapes EPA data every hour and compiles those numbers in a running spreadsheet. That sheet feeds a web embed that I built for display in Denverite stories and in our newsletter.
This is generated by a program that scrapes state data every day and compiles the numbers in a spreadsheet, which feeds the graph. The graph lived in a web embed that was embedded on Denverite and in the newsletter – it became outdated when COVID case rates ceased to be relevant (in part due to at-home testing), so I stopped updating it. We still use the CDC transmission rating in our daily emails.
