DeltaGraph, originally from DeltaPoint and later SSPS, was a powerful
business and scientific statistical graphics package for the Apple
Macintosh and Microsoft Windows.

It competed against Stanford Graphics, but less so with business
graphics-only packages like Excel.

No relation to Boeing Graph. :P

Using with Adobe Type Manager 2.0 is recommended for use on Windows.
