Tableau visualization about HIV research

Dr. Erica Jacobs and her team at Rockefeller University made huge strides in understanding HIV, but they knew they could get more from their data. Using both published and unpublished data from their study I reworked their initial charts, added animation and interactivity, and uncovered some new and potentially very important information hiding in the results.
Tableau visualization about the gap between the rich and poor

The Economist attempted to show that the gap between the rich and poor is growing, but their chart didn't show that. I reworked the data to show the story in a more accessible and compelling way. Now, you can see that the gap in Italy has grown almost 400% in 15 years.
Numbers aren't the only form of information that needs good visualization. The original on the left was provided by the CEO of a major network provider to explain how the various parts of the company's subdivisions work together. The graphic on the right is my interpretation of the same information.

Financial data is, of course, the bread and butter of data visualization. Here is a simple interactive dashboard of sales data for a year broken out by the contact method (email, newsletter, both, or neither). In the interactive version, you can see the data by month, quarter, or year.
See below for a tutorial on how to make the ring chart in this dashboard.

Tableau dashboard showing user scores by MPAA rating

This dashboard looks at Netflix's history, and how users have scored movies by the original release date. I found a fascinating division in the data when I sorted by MPAA rating - the younger audience shows have a much lower rating. Perhaps parents are sick of Barney?
