I've also posted this over on the Before Watchmen thread but I'll mention it here as well. I've played around a bit more with the diagram formatting and figured out how to include the cover thumbnail with the title and ship date beneath it. It bumps up the size of the diagram considerably. I used the Before Watchmen titles since I was doing this by hand and there were a lot fewer issues and titles to deal with:

It is a large image with 5904 pixels by 2585 pixels and is about 827 KB.
Let me know what you think of the format. One I automate the process, I'd like to do this for the New 52 and possibly the Marvel Now titles.
I'd also appreciate any help people would like to offer collecting data for the New 52 diagram. Specifically, I'd like to include in the diagram any/all footnote references and explicit reading order notes included in the comics. For instance, here is the data I have for "The Culling":
Teen Titans (2011) Annual #1 -> Superboy (2011) #9 [Crossover: The Culling];
Superboy (2011) #9 -> Legion Lost (2011) #9 [Crossover: The Culling];
Legion Lost (2011) #9 -> Teen Titans (2011) #9 [Crossover: The Culling];
Teen Titans (2011) #9 -> Ravagers (2012) #1 [Crossover: The Culling];
And for "The Night of the Owls":
Batman (2011) #8 -> Nightwing (2011) #8 [Crossover: Prelude to the Night of the Owls];
Nightwing (2011) #8 -> Detective Comics (2011) #9 [Crossover: Prelude to the Night of the Owls];
Detective Comics (2011) #9 -> Batwing (2011) #9 [Crossover: The Night of the Owls];
Batwing (2011) #9 -> Batman and Robin (2011) #9 [Crossover: The Night of the Owls];
Batman and Robin (2011) #9 -> Batman (2011) #9 [Crossover: The Night of the Owls];
Batman (2011) #9 -> Batgirl (2011) #9 [Crossover: The Night of the Owls];
Batgirl (2011) #9 -> Birds of Prey (2011) #9 [Crossover: The Night of the Owls];
Birds of Prey (2011) #9 -> Catwoman (2011) #9 [Crossover: The Night of the Owls];
Catwoman (2011) #9 -> Red Hood and the Outlaws (2011) #9 [Crossover: The Night of the Owls];
Red Hood and the Outlaws (2011) #9 -> Nightwing (2011) #9 [Crossover: The Night of the Owls];
Nightwing (2011) #9 -> Batman: the Dark Knight (2011) #9 [Crossover: The Night of the Owls];
Batman: the Dark Knight (2011) #9 -> All Star Western (2011) #9 [Crossover: The Night of the Owls];
All Star Western (2011) #9 -> Batman (2011) Annual #1 [Crossover: The Night of the Owls];
For footnote references, replace "Crossover: " with "Footnote: "
So far, I don't think DC is doing too many crossovers but there are a lot more in the coming months.
Any suggestions on the look of the timeline diagrams would be appreciated.
