This flipbook has its origins in a presentation I made at The Data Warehousing Institute (TDWI) annual show, in Washington, DC, in April of 2011.

The materials from that presentation could not -- by the nature of the form, the venue, and the expectations of the audience -- encompass an extended discussion of (or perhaps it’s a diatribe on) the emerging models of data visualization for streaming data -- so I built this flipbook to make that argument.

It’s a perpetually-changing document; as the argument forks, execs or crashes, I recode it. As better examples become available, I add or replace stuff.  As I figure out what I am actually talking about, the structure of the space morphs. That is the nature of emergence, of flux.

As with streaming data -- you’ll probably not step in this river, and find it in the same state, twice. If you do, it’s not a river any more, is it?



Heraclitus (c. 540 BCE - 375 BCE) is a pre-Socratic philosopher whose work we know only because fragments of it are preserved in the writings of other, later writers -- an oddly appropriate fate for a thinker whose fundamental notion was: everything is flux, and nothing abides.

Heraclitus -- in fragments -- is the patron saint of streaming data.
