I just downloaded the tornado data. Seems like everyone with Tableau is using it as it's amazing. I didn't even notice it had latitude and longitude data. I don't know why I totally missed that.
This is the most beautiful application of tableau i have ever seen i could never imagine that we can use trigonometric functions to make image (afgan girl) in Tableau,Still i am not able to figure out how to do that, any one can help with some clue.......... Thanks Matt and ken for wonderful session and highly informative content witten by both of you on web
You can see all the details on our websites, www.kenflerlage.com and www.sirvizalot.com. Matt and I have written blogs about pretty much everything we showed in our presentation. If you want to see how to create "loom art" (Afghan Girl) specifically, then search my site for loom art. The blog includes details about the inspiration to create this (Chis DeMartini), the code used to generate the data, and the process for building it in Tableau.
