it depends on what kind of data you are desplaying. if there is only one type of data that is all related and conected, a line graph would be a good thing to use.
Sometimes it is, other times it is not. If you want to display the favourite fruit of a school class, a continuous line graph would be totally useless.
It shows the amount of the surveyed matter or other sets of data. They are good comparing sets of the data that just have an amount.
It's impossible to tell unless we have both the graph and the set of data.
A graph that displays data by using points joined together by line segments.
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 chart would be good for continuous and discontinuous data, as for the environmental variation would be a diagram.

It really depends upon what information you're trying to represent. If you're trying to show trends in data, then a graph would be good. If you want to show links with things, then a chart is good. Tables are useful for showing data if you don't want to compare it
Often a picture is worth a thousand words. Some people are not very good at translating words into visual images. If you can show them what you mean in a chart or graph, you give the data a substantially greater visual impact in much less time.
a bar graph shows unrelated data, so use one when you are showing unrelated data. :)
A graph does one thing that a data table doesn't do, which is allow a visual representation of the data to be created. This would allow you to see, for example, that a series of data points rises in a straight line far more easily than a bunch of numbers in a table would. Additionally, graphs are good for comparing data, say volumes or masses for example, so that you can see how one value compares to another. All in all, it allows you to see all the data points at once, compared to each other, so that you can draw conclusions about the data as a whole.
