Welcome to Revolution: you can now leave most externals behind.  :)

With the Rev engine being orders of magnitude faster than most other xTalks
(and a good many lower-level languages) and with a richer object model, you
usually don't need externals for most things they're used for elsewhere.  In
the dozens of HC and SC projects I've ported I've replaced every external
with native Transcript calls.

Here's a handler for making pie charts to get you started -- you can craft
others for line and bar charts:
