I'm a big fan of xkcd.com and the humorous-yet-informative charts Randall produces. Additionally, I'm thinking of designing something to help people new to roleplaying and D&D figure out what race/class might best suit them, without overwhelming them with 3 handbooks' worth of information. So, having compiled the information from the handbooks on a spreadsheet (or two) and inspired by a webcomic, I present to you a bunch of Excel charts.
Please note, these have all been scaled to 350 px wide, clicking on the images will open up the full size chart. Also, this only incorporates data from the three Player's Handbooks - it does not include any campaign-specific source material (Eberron, Forgotten Realms, Dark Sun).
Some info on the Races of 4th edition
