Drawing and animation in Matlab

Hello, I'm sorry for my English, but I hope you will understand me right)
I want to visualize data in Matlab - plot some lines, cycles and other objects according to the matrix. For example:
I have 3 different states, shown in circles, and matrix, which contains the path of these states (See Figure) http://dl.dropbox.com/u/2827213/Stuff/Pics/Scheme_Plot.png How can I plot cycles, pathes and animate it- refresh every time with matrix changing.
I'm sure that there are instruments in Matlab for my purposes, but I can find it. Can you help me?

I hope I'm not doing your homework
clf
a=[1:3;1:3;1:3;1:3;1:3];
plot(a,'bo','MarkerSize',25)
axis([0 6 0 4]);
%c=[3 3 2 1 1]
c=[1 2 1 3 2]
%c=[3 3 3 2 3]
for b=1:4
line([b b+1],[4-c(b) 4-c(b+1)],'Color',[1 0 0])
pause(1);
end

Doh. Too late. Still, how's this:
paths = [3,3,2,1,1;1,2,1,3,2;3,3,3,2,3];
[m,n] = size(paths);
th = linspace(0,2*pi);
r = 0.3;
x = r*cos(th);
y = r*sin(th);
for k=1:m
for j=1:n-1
line([j,j+1],[paths(k,j),paths(k,j+1)],'color','k','linewidth',2)
end
end
for k=1:m
for j=1:n
patch(j+x,k+y,'w')
line(j+x,k+y,'color','k','linewidth',2)
end
end
axis([0.5,n+0.5,0.5,m+0.5])
set(gca,'XTick',[],'YTick',1:m,'DataAspectRatio',[1 1 1],...
'YDir','reverse','Box','on','TickLength',[0,0])
If you like it, I can add animation.
EDIT: because I'm a dork, I added animation, whether you like it or not. So combining some of Paulo's ideas, which I thought were cute:
paths = [3,3,2,1,1;1,2,1,3,2;3,3,3,2,3];
[m,n] = size(paths);
pmax = max(paths(:));
h = zeros(n-1,m);
for k=1:m
for j=1:n-1
h(j,k) = line([j,j+1],[paths(k,j),paths(k,j+1)],...
'color','k','linewidth',2);
end
end
[x,y] = meshgrid(1:n,1:m);
line(x(:),y(:),'Linestyle','none','LineWidth',2,'Color','k',...
'Marker','o','MarkerSize',25,'MarkerFaceColor','w')
axis([0.5,n+0.5,0.5,m+0.5])
set(gca,'XTick',[],'YTick',1:m,'DataAspectRatio',[1 1 1],...
'YDir','reverse','Box','on','TickLength',[0,0])
set(h,'visible','off')
for k = 1:m*(n-1)
pause(0.5)
set(h(k),'visible','on')
end

We are crazy for new challenges because we learn alot from them and improve our matlab skills :)

Just a little more fun... (adding on to Matt's and Paulo's ideas)
% paths = randi(5, [4, 6])
paths = ceil(5*rand(4, 6))
[m,n] = size(paths);
mx = max(paths(:));
set(gca, 'XLim', [0, n+1], 'YLim', [0, mx+1], 'YDir', 'reverse', ...
'Box', 'on', 'XTick', [], 'YTick', []);
h = line(NaN, NaN, 'LineWidth', 3, 'Color', 'Black');
[X,Y] = meshgrid(1:n, 1:mx);
line(X(:), Y(:), 'LineStyle', 'None', 'Marker', 'o', ...
'MarkerFaceColor', 'white', ...
'MarkerEdgeColor', 'black', 'MarkerSize', 20);
pt = line(NaN, NaN, 'Marker', 'o', 'MarkerEdgeColor', ...
'none', 'MarkerSize', 18);
for id1 = 1:m
title(num2str(paths(id1, :)));
for id2 = 1:n
set(h, 'XData', 1:id2, 'YData', paths(id1, 1:id2));
for id3 = 1:100
set(pt, 'XData', id2, 'YData', paths(id1, id2), ...
'MarkerFaceColor', 0.01*id3*[1 1 1]);
drawnow;
end
pause(0.5)
end
end

Nice and compact code, it gave me more ideas but I'm keeping the original problem size, I added the ball animation and a loop to the demo.
