Simulate Circle which center is at real Lat and Lon

I want to put a circle at specific center with latitude and longitude with a known radius.
However I dont have any idea how to make it. Because latitude/longitude can be negative/positive all the time, what varies is the distance. So I dont know how to simulate my position based on the circle.

Negative and positive coordinates are common when drawing circles...

Construct a circle of the correct radius centered around (0,0), then add the longitude to x and the latitude to y (if you are using the convention that north corresponds to increasing y values.)
