Some of the staff where I work are interested in a demo of Tableau. Basically they want to know what it is, how does it work, and how we are using it. So I downloaded the FDIC Failed Banks list from Data.gov and used this data set to show them how easy it is to create a quick interactive data visualization that can be embedded into a blog post. I actually made this right in front of them as part of the demo. It took about 10 minutes max.
Nothing fancy, and there are others who have done this as well, but it is a heck of a lot better than my previous viz using this same data. This actually makes me happy because I hope it is showing a certain level of growth in my skills and understanding of data visualizations.
