Date slider with a Map

I'm trying to determine how to create a report that does the following.

My data is very simple and is composed of 3 columns:

• State name
• Rating.  A value from a small set of available values.  Think:  Low, Medium and High.
• Date. The date is likely not every day but a date per month or date per week, like Jan 1, 2020, Feb 1, 2020, etc.

Assume that there is an entry for every combination of state-rating-date within a given date range, like every month in a given year.

I want to display this using a map of the United States where the legend is based on Rating.  For example, Low = Red, Medium = Yellow and High = Green, and the map would show each state with the appropriate color.  

Last, I want to add a single-value slider based on the Date, with a minimum value of the first date and a maximum value of the last date.  It would default to the most recent date.  That means when the report first appears, it would show the state-rating values in the map where the date = max(date).  Then I can use the slider to view the state-rating values for any specific date in the date range.. It would be very dynamic, so as I moved the slider the colors of the map would change accordingly to match the value of the selected date.
