The document contains C code to create a bar chart using graphics functions in C. It initializes the graphics mode, sets colors and styles, draws the axes and labels for the bar chart. It then draws 5 bars of different colors and patterns at specified x-y coordinate positions to represent the bar chart. Finally it waits for user input before ending the program.
