Cat: Data Visualization
Here is a use of a D3 sunburst visualization (partition layout) with data that describes sequences of events.
In this use case we summarize navigation paths through a web site. The visualization makes it easy to understand visits that start directly on a product page (after landing there from a search engine), compared to visits where users arrive on the site’s home page and navigate from there. A funnel lets you understand a single pre-selected path, this allows you to see all possible paths.
