UPDATE: The presentation is online:
I gave a presentation on data visualization at Ignite Salt Lake last night, and I thought it went pretty well. (I wasn’t hiding my face and sneaking out of the theater afterward.)
Here are the slides from the night with my notes.
I’ll post video as soon as it becomes available.
Below are links to the visualizations that I referenced:
Slide 3 (overview): Visualization of the Stimulus Bill
Slide 5 (Ask a question, tell a story): Charles Minard’s info vis of Napoleon’s march
Slide 9 (Size Visualization Example): Edgar Allen Poe’s “The Raven” visualized with Wordle
Slide 11 (Color Visualization Example): Map of the Market – stock market visualization
Slide 13 (Location Visualization Example): Map of flights in the US in a 24 hour period. This actually uses color to indicate altitude (darker is higher, lighter is lower, but I didn’t have time to go into that in my talk.
Slide 15 (Network Visualization Example): My Facebook friends as graphed by Nexus Graphs
Slide 17 (Time Visualization Example): The Baby Name Voyager – an information visualization on when people name their babies what
Slides 18 – 20 (How Much Is a Trillion Dollars?): Visualization of a Trillion Dollars

Visualizations I didn’t use, but that are still cool
Google Heat Map of where users look when they get a Google search result (scroll down a bit)
Twitter network browser – this one is more fun to play with than it is useful
