Exploring and Explaining Science

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 Using both published and unpublished data from their study, I reworked their initial charts, added animation and interactivity, and uncovered some new and potentially very important information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.

Revenue & Margin
Actual vs Budget
Simulator
Financial data, especially for sales, is a mainstay in data visualization. This executive report looks at revenue, expenses, and margins for a fictional company that cleans wind turbines. There is a significant amount of interactivity and is a tool for the executive team to reflect on the past, stay abreast of the current, and plan for the future.

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.
Media Consumption

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?
Infographic: Before and After
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.

Exploring new types of charts and layouts is fun - and critical part of growing skills. Here is an early example of learning what Tableau can do. See a tutorial I wrote on how to make this ring chart.
