I experimented with Tableau years ago. One of the most interesting things to me was OData. Back then, I thought it would be great to be to get information directly from a financial report into Tableau and present the information. Guess what. 28msec now supports OData.
When I found out that 28msec supported OData, I took their demo link, pasted it into Tableau (I had to upgrade from version 8.2 to the current version which is 9.3), and I created this. It does not look that great, but I just wanted to prove that the 28msec atom-xml feed actually worked in Tableu, which it does.
I would encourage people to experiment with the 28msec queries an Tableau. Here are a bunch of example queries. There is documenation that will help you create queries at the bottom of the blog post. If you come up with anything good, let me know.
