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. Continue reading 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. Continue reading Trifacta Wrangler for cleaning and reshaping data
Jon Schwabish is running a blog and podcast called PolicyViz. In both, he talks about communicating data and how to deal with numbers for the general public. He recently had two interesting guests back-to-back on his podcast: Nigel Holmes and Edward Tufte. Both episodes are well worth listening to.
Conventions in visualization can seem arbitrary, and quite a few are. But there is also a vast body of research, and it is growing every day. Just how does visualization research work? How do we learn new things about visualization and how it can and should be used? Continue reading Visualization Research, Part I: Engineering
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. But what is still lacking is the metadata, making analysis harder than it needs to be. Continue reading Why Is Metadata So Hard?
Ben Shneiderman has put together a series of postings about the Pioneers of Human-Computer Interaction (HCI). Each includes a brief biography, some personal notes by Ben, as well as Ben’s photos of them. The latter are particularly remarkable, often going back to the 1980s – like the gem at the top of this page, showing the man himself in 1986.
When creating charts, it’s important to pick the one that actually fits not just the data, but the task. That can require going outside your comfort zone to use something beyond the four or five most common chart types. Here is an example where the original chart does not support comparison between two different sets of numbers, but it’s easy to fix. Continue reading The Point Of A Chart
Last week, I gave one of the visualization primer talks at BioVis in Dublin. My goal was to show people some examples, but also criticize the rather poor visualization culture in bioinformatics and challenge people to do better. Here is a write-up of that talk. Continue reading Talk: How to Visualize Data
People from Georgia Tech, INRIA, University of Stuttgart, and other institutions have put together a comprehensive dataset of all papers presented at Vis/VisWeek/VIS since 1990. This was first collected for a set of visualizations last year, but has been updated with the 2014 data. They intend on keeping it up to date.
