Hi all, visualization developer here.<p>The idea for the visualization comes from my challenges working with user session data in several tech companies (however, it can readily apply to process data in manufacturing and services industries, sequences of plays in sports, etc). Raw events/logs are usually considered hard to work with, so it is common to collapse them into key metrics/dimensions and plot those in dashboards. This works well for basic reporting but not so much when one needs to root cause observed changes/differences in metrics or wants to explore data to find product gaps/opportunities. Here are a couple of very common questions: why have conversions dropped in an updated UI? What do users do when they don’t convert?<p>Additionally, SQL-based tools, which are commonly used for analytics, are pretty inefficient for querying sequence data. Most table schemas and query languages assume metrics/dimensions data structure, which doesn't readily lend itself to asking questions about the order and relationships between events in the same stream.<p>With this data visualization, I am exploring two major questions:
how to visualize sequence data in an intuitive way?
how to intuitively ask questions of sequence data?<p>To play with the first question, try hovering, clicking, double-clicking, right-clicking, long-clicking and dragging on the Sunburst graph. To explore the second question, read through a few examples of the query language below the graph and then try adding a few queries into the “Rules to filter & modify sequences” widget. This is just a prototype, so can be rough around the edges.<p>Would love to get your feedback and ideas for improvement! Especially curious about interesting questions, which the visualization can’t help answer yet, and ideas how to add that capability. Would also appreciate ideas for other popular datasets to plot. If you have a business sequence dataset, which you’d love to try with the visualization, please reach out to me over the email in my profile.<p>Thanks for checking out the data viz and happy to answer any questions!
