Hi, I was wondering if there was an algorithm that would help me locate a concentration of elements in a cartesian plane, I mean their locations are too close together, it would be easier to explain with a picture, but I am unable to upload an image.
Let's say there are a lot of elements in the plane and I want to draw a circle with a diameter of 3 units enclosing at least 3 elements, the algorithm should tell me where that circle should be drawn.
