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 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.
A graph that displays data by using points joined together by line segments.
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.
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 would be a good choice to highlight the differing amounts of product created under different conditions. Bar graphs are a good choice when comparing a few pieces of data to each other.

When you want to display data over a length of time.
a bar graph shows unrelated data, so use one when you are showing unrelated data. :)

That depends on the data you're trying to graph. Generally, circle graphs / pie charts / whatever you want to call them are good because they show pieces of data in proportion to the sum of all the data; that is, they illustrate the relative size of the pieces of data when compared to each other and compared to the whole.
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
The bar graph is best suited to show the frequency of categorical data, like how many of a type of cookie is sold, or how many girls and how many boys get good grades.
Viewing the data is an easy way to see some of their characteristics such as trends, seasonality, outliers, relationship between variables (linear, quadratic, power etc).
