bulgaria_plot records the population in Bulgaria from 1887 to 2022. The graph should plot the data points as circles, and connect consecutive data points with straight line segments to suggest a curve.

• bulgaria_data.txt, the data.

bulgaria_plot_dislin() uses dislin():
• bulgaria_plot_dislin.c, reads the data and displays a line plot.
• bulgaria_plot_dislin.sh, runs the test.
• bulgaria_plot_dislin.txt, the output file.
• bulgaria_plot_dislin.png, the plot.

bulgaria_plot_gnuplot() uses gnuplot():
• bulgaria_plot_gnuplot.c, reads the data and displays a line plot.
• bulgaria_plot_gnuplot.sh, runs the test.
• bulgaria_plot_gnuplot.txt, the output file.
• bulgaria_plot_gnuplot.png, the plot.

bulgaria_plot_matlab() uses MATLAB():
• bulgaria_plot_matlab.m, reads the data and displays a line plot.
• bulgaria_plot_matlab.sh, runs the test.
• bulgaria_plot_matlab.txt, the output file.
• bulgaria_plot_matlab.png, the plot.

humps_plot evaluates the function y=humps(x) over the interval [0,2] and creates a plot. No data file needs to be read. Several graphics packages are used.

humps_plot_dislin() uses dislin():
• humps_plot_dislin.c, creates the data and displays a line plot.
• humps_plot_dislin.sh, runs the test.
• humps_plot_dislin.txt, the output file.
• humps_plot_dislin.png, the plot.

humps_plot_gnuplot() uses gnuplot():
• humps_plot_gnuplot.c, creates the data and displays a line plot.
• humps_plot_gnuplot.sh, runs the test.
• humps_plot_gnuplot.txt, the output file.
• humps_plot_gnuplot.png, the plot.

humps_plot_matlab() uses MATLAB():
• humps_plot_matlab.m, creates the data and displays a line plot.
• humps_plot_matlab.sh, runs the test.
• humps_plot_matlab.txt, the output file.
• humps_plot_matlab.png, the plot.
