title: Plotting a filled circle around a XY-coordinate point, with the radius corresponding to actual geographical distance
body: <p>I have a set of geographical coordinate points (E, N) and I want to plot them on Matlab. The coordinates of the data are measured in meters, for example a coordinate point of E = 35000, N = 756000 means a point on the map 35 km to east from the origin and 756 km north from the origin. </p>
  
  <p>What I want to do is plot these coordinate points in a Matlab plot. This is easy, but what I also want to do, is to select a specific coordinate point and plot a filled circle around the point, with the radius of the circle (given as a parameter) corresponding to actual distance (in meters) in the geographical map. </p>
  
  <p>The image below will explain my question (even though the circle is not filled): </p>

  <p>How would this be done easily on Matlab? Any ideas? =) Please let me know if my question is unclear :) </p>
  
  <p>Thank you for any help! =)</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>here is the result I got using user natan's code: </p>
