Plotting data on a geographic map

[OBUM EZEANOSIKE]

Dear All,
I am trying to plot data on a Map of Nigeria (showing states, their city data was generated, and the geopolitical zone of the country the state belongs (such maps exist already)
It is the data of prevalences of a disease, but I need to show the states/cities/geopolitical zones where the prevalence of that disease was determined.
I will appreciate guidance

The data showing the states/city and the geopolitical zone is shown below
