It's especially useful when comparing values that are NOT a series. For example, the latest unemployment rate in Louisiana, New York, and California.
The data should be for comparable samples (1 year; one location, etc.)
Typically, the bar should start at the "0" point for the sample, or, if not, the scale should be clearly labeled and/or explained.
(Although a bar graph can be used as well, a line graph, where values are linked by a line that slants up or down with the data points, is a nice choice for a series of values, such as "the population of New Orleans, 2000-2006.")

Visual impact is stronger and you can do comparisons much easier.
