How to insert multiple circles on selected points on an image?

Hello, I am trying to find the (x,y) coordinates of 14 points on an image and draw circles and label them with numbers.

I have the following code. I am able to find the coordinates, however, it's only showing one circle on the last point I select. Can someone please help me and figure out what I am doing wrong? Also, how do I insert numbers along with the circles?

Thanks in advance!

%%
moving=imread('biopsy burn 2.JPG');
imagesc(moving);
[x,y]=getpts;
pos=[x,y];
for i = 1:length(pos)
shape=insertShape(moving,'circle',[pos(i,:),40],'LineWidth',10,'Color', 'White');
end
figure
imagesc(shape)

I don't have CVT, so I can't test this, but you're never saving the output of shape. Each time, you're starting from the source image.

You shouldn't need to use the loop anyway. InsertShape() accepts a point list directly

% should be able to pass a list of all points and radii in one call without the loop
shape=insertShape(moving,'circle',[pos,40*ones(size(pos,1),1)],'LineWidth',10,'Color', 'White');

See the section on the 'position' property:

As far as text labels go, you should be able to use insertText(), which can similarly take multiple points at once.

Thank you so much! I was wondering if you would be able to help me with this part too!!
