It can be, but not necessarily.
If I had the heights (continuous variable) of a class of students I might use a histogram. Conversely, if I had the number of cars (discrete variable) driving by every minute, I would use a line graph. It all depends on which kind of graph conveys the information to your audience in the best way.

A broken line graph shows information by plotting points of information on the graph and are connected with a line. This is used to show continuous data.
A line graph is not a good way to represent the data as the number of CDs is a continuous variable, but the artists are a discrete, categoric variable. A line graph should be used when both variables are continuous. A bar chart or bar graph should be used when one variable is continuous and one is discrete.
A bar graph consists of columns of varying height to show data - looking like 'steps' across the page. A line graph uses a continuous line which changes direction with each piece of data.
Straight line graphs show continuous data (like your distance from something over time). Ones that have skips in the line are representations of noncontinuous, or discrete data (like how many papers you have in a folder).

A broken line on a graph typically represents a discontinuity or missing data points. It can also indicate that the data points may not be continuous or that there is a gap in the data being presented.

line graph
A line graph is useful for showing trends or continuous change. Other kinds of graph also will show these, but a line graph is usually clearest.
A line graph, not surprisingly!
