you could do like this
loglog([ 10^2 10^2 10^4 10^4 10^2],[ 10^4 10^6 10^6 10^4 10^4]);
hold on;
loglog([ 1 10^2 10^4 10^4],[ 10^2 10^2 10^1 1]);
loglog(10.^([5 6 7 8 5]),[ 10^3 10^5 10^5 10^4 10^3]);
grid on;
axis([1 10^8 1 10^8])

The graph doesnt have to be a log graph as seen in the example, just the same concept showing the shapes.

As @Jonas shows, you can just plot points in sequential order to draw the lines -- each line will be a vector of x,y points from your data.
The perfect rectangle can be done with the rectangle function, the other areas could also be done with patch with no fill...
It'll perhaps be somewhat tedious, but not particularly difficult.
NB: You ca put all your data into single X,Y arrays by column -- if there aren't the same number of points to define each line, fill the remainder of the column to make the rectangular array with NaN; plot() will just silently ignore those entries.
This will let you get by with one call to plot() rather than having a long string of duplicated code with a bunch of named variables.
Create a matching array of labels to use for the indentifying text.
