This document discusses how to set up graphics programming in C using SDL and libgraph libraries on Ubuntu Linux. It explains that SDL is a cross-platform multimedia library for accessing graphics, sound and input devices across platforms, while libgraph implements the Turbo C graphics API using SDL. It then provides step-by-step instructions on installing prerequisite packages, downloading and compiling libgraph, and compiling a sample C program to draw a circle using the libgraph library.
