1010data's web UI isn't actually based on the K2-era GUI framework; it is architected as a reasonably conventional web application that happens to use K3 as a server-side language. The 1010data query language offers facilities for making data-driven UIs for interactive reports and the like, but any semantic similarity to the K2 GUI system is probably coincidental.

Hardly coincidental! I very much had the K gui in mind when I originally architected it (and I'm not sure I'd describe it as a "reasonably conventional web application"...)

So 1010data's purpose is to sell analytics tools to kdb+ users? Does kdb+ not come with a simple way to pipe output to a chart? For the price, I'd hope they had something more than a REPL.

1010data's analytics tools and database are entirely their own product, developed separately from kdb+. While these are implemented in K (K3, which precedes kdb+/q/K4), the end users are not K programmers any more than WordPress users are PHP programmers.
