Your image looks like sets of triangles. Let each triangle have 3 x and 3 y and you can call the following script for each triangle:

% create you triangle points, one created here 
x=[1 10 5];
y=[10 25 45];
% create figure and hold on it
figure; hold on;
% below can be placed in a function
plot([x(1) x(2)], [y(1) y(2)], 'bo-');
plot([x(2) x(3)], [y(2) y(3)], 'bo-');
plot([x(1) x(3)], [y(1) y(3)], 'bo-');
for i=1:3
   text(x(i), y(i), ['\{' num2str(x(i)) ', ' num2str(y(i)) '\}']);
end
