If you want to explore - go to the linked site, tell your browser to SAVE the link on the "Raw" button. This will give you a text file - it's actually a comma-delimited .csv file. Open Excel, ask to Open the file, and in the dialogs that open, specify that it's a comma-delimited file. That will pull the data nicely into columns.
You can then use Excel filters to view only a single state's data, or a single county's data.
I pulled the Bucks County data into a separate spreadsheet, and generated an area graph, showing new cases as a portion of total cases - because it's the growth in new cases that's the most important thing to watch. When that plateaus or declines, we're getting somewhere...
The Bucks data looks to be pretty accurate through 3/25; 3/26 shows zero new cases, and we know that's not up to date. The county website is reporting 181 cases (presumably as of either COB yesterday, or early today).
