Visualization Strategies: Hierarchical Data » Tim Showers - Web. One of the most challenging types of data to convert into a chart or visualization is also one of the most common: Multi-Level or ‘Hierarchical’ data.
Perhaps every category of data is composed of sub-categories, or a change in one data point has a major effect on surrounding data, but regardless, the standard library of charts and graphs doesn’t offer much in the way of making hierarchical data clear, so here are a few alternatives: Nested Categories: Treemaps: Recently “Treemap” style charts have come out of their origins in academia into common use.

Each category is sized according to what percent of the total it takes up, and child categories can be placed inside parents in a similar manner.

Although it is a fact that most of these 4 billion people do not use smartphones able to do more advanced computing task, it is indeed an interesting thought to consider the mobile device as the actual incarnation of the ubicomp vision, as has already been argued by Bell & Dourish (pdf file: ‘Yesterdays Tomorrows’).
