Vizable, data worlds for iPad
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.
Vizable is built on the idea of data worlds, which depend on the type of data and the kind of question you have. For people who know Tableau, this is a completely different way of doing things. Vizable is not a toolkit to build a myriad of different kinds of visualizations, but focused on looking at particular kinds of data.
Each of the worlds represents a playground to work with a specific type of primary data, like time and categories (for now). The way the data is shown in each is likely to allow you to answer most questions: bars for categories, lines with histograms for time series, per-category histograms for measures other than count, etc.
A single view of data would be pretty boring, and no different from lots of other charting tools in the AppStore. What sets Vizable apart is the rich set of interactions. You can filter, add columns to compare, zoom into time in really interesting ways, etc. Filters work across worlds, so you can switch back and forth between them and look at your data in different worlds.
Vizable was built specifically for touch. How do you filter using touch? How about inclusion versus exclusion filters? How do you work with multiple measures at the same time? How do you sort? How do you drill down into hierarchical categories? How do you navigate a time series? Etc.
The beauty of the seeming simplicity is that it makes a lot of complex features very approachable. You can almost literally touch your data to interact with it, it's pretty cool.
Vizable is available now, for free, on Apple's App Store.
