Dashboard Question



working on a project where I'm tracking the completion of IT equipment refresh across 170 sites. Long story short my leadership wants to see a dashboard that looks similar to the very poorly sketched image below. Basically, they want to see out of 170 sites, what percentage of sites have completed:

Task 1

Task 2

Task 3 etc

with some type of calendar to show where we within the month. The only thing I can think of is a Gant chart but that is not a dashboard. Any ideas would be appreciated. If you have any questions about my project please ask
