<p>Some of the answers of Dmitri Pavlov, particularly <a href="http://mathoverflow.net/questions/20740/is-there-an-introduction-to-probability-theory-from-a-structuralist-categorical-p/20820#20820" rel="nofollow">this one</a> will be helpful to you. Segal's 1965 <a href="http://www.ams.org/journals/bull/1965-71-03/S0002-9904-1965-11284-8/S0002-9904-1965-11284-8.pdf" rel="nofollow">Algebraic integration theory</a> is also a good place to look; he walks you through for example how to view a measure space as a "spectrum" of an algebra of random variables (e.g. the unnumbered theorem on page 432).</p>

<p>Diagrammatic notation for tensors (Penrose diagrams, birdtracks, etc.). It makes many things like the invariance of tr(A B C) under cyclic permutation into empty statements.</p>
