Almost any kind of graph can be used to show discrete data: You can use a line graph (most economic data), a bar graph (Demographics), a pictogram, a pie chart, a scatter plot, radar.
Although 3-d charts can also be used, they are very poor at conveying information because of the difficulty in interpreting depth.

Any kind of graph can be used for discrete data.
The way you can use graphs of polynomial functions to show trends in data is by comparing results between different functions. The alternation between the data will show the trends. Time can also be used to show the amount of variation.
To show the results of an experiment or test.
graphs
A pie chart :) or a bar graph.
Line graphs are used to display data to show how one variable (the Responding variable) changes in response to another variable (the Manipulated variable).
