I need to make a nicer-looking version of this image:
Is there some program that generates these graphs? Or are they done by hand in something like Visio?
(I'm on Mac OS X, and I have access to Windows if needed)

Try Graphviz.
Sage can generate graphs. It's like Mathematica/Maple but it's open source and free.
The igraph library for R allows you to plot graphs. Combined with tikzDevice, it can also produce LaTeX output of the plots.
Here's an example:
The graph itself was produced using the R code
g <- graph.empty() + vertices(letters[1:3]) g <- add.edges(g,c(1,2,2,3,3,1,2,2)) g <- as.undirected(g)
and was plotted to a LaTeX file using the R code
tikz("~/Dropbox/Thesis/Thoughts/temp.tex",standAlone=FALSE,width=4,height=4) plot(g,layout=layout.fruchterman.reingold,vertex.size=30,edge.width=3,edge.color="black") dev.off()
Since no one else has mentioned it yet, yEd, a free diagram/graph editor.
I've found Gliffy to be a great method of doing this, and it has the advantage of being totally web based--nothing to install or screw up across operating systems.
Try Gephi is a open source mac for graphs....http://gephi.org
Just adding one other option. TikZiT seems to bee a multi-platform GUI tool that can generate TikZ code (for inclusion in LaTeX documents). Together with QtikZ/Ktikz this can be used to quickly produce pdf and/or png versions of a graph.
Simple, online, free
If graph layout does not matter you can use Wolfram Alpha
Graph 1->2, 1->3, 2->3, 2->2
