My colleagues at Tableau Research have three papers at InfoVis next week. They cover guided data exploration, color theory, and data partitioning. Here’s a little preview. [Read more…] about Tableau Papers at IEEE VIS 2015
Tableau today released a new visualization tool for iPad, called Vizable. This is a completely new app built specifically for exploring data using touch. It is based on a new approach to visual analysis that focuses on the data and task, rather than providing a chart toolbox. [Read more…] about Vizable, data worlds for iPad
Wrangling data into a shape that can be used to create visualizations is a huge problem with few available tools. Trifacta Wrangler is a powerful new tool that is free to use. [Read more…] about Trifacta Wrangler for cleaning and reshaping data
The U.S. Department of Education just released an amazing dataset about the costs of going to college, earnings potential, etc. They’re doing so many things right, it’s really great.

Feedback loops are a common concept in engineering. When it comes to giving talks, academics would do well to apply some of the thinking behind them to improve their output by observing how it deviates from the desired one, and making changes to adjust it.

Last week, I had the pleasure of attending the CHI 2015 conference in Seoul, South Korea. CHI technically stands for Computer-Human Interaction, but it has become a name rather than an acronym in recent years. And CHI’s scope is very broad, it covers many areas that are not strictly part of HCI (Human-Computer Interaction – why use one acronym when you can have two?).
