DR Graph is a business graphics creation program. It can create line,
bar, pie, and scatter graphs and print them on a graphics printer. DR
Graph is implemented using Digital Research's GSX graphics library,
and can run on many different platforms. Because it is implemented
using shape-based graphics, it can scale up with higher resolution
displays or plotters.

It was available on the IBM PC platform both for DOS and CP/M-86. It
was also available for many Z-80 based CP/M-80 machines and non
IBM-compatible DOS machines. Because of the flexible GSX driver-based
architecture, it could make use of higher resolution displays with
just the addition of a driver. Today a VGA driver is available:
