Actually, they are useful. At least in some cases.
Bar graphs are usually used for comparing. You could go into more detail, but that's the gist of it..
Most graphs: Pie charts, bar graphs, histograms, scatter graphs can all be used.
Bar graphs are used to display countable data that are grouped in categories.
A bar graph is used to show different totals in different categories.
Yes - in the usual orientation of bar graphs. However, bar graphs can be horizontal.

Bar graphs are usually used for comparing. You could go into more detail, but that's the gist of it..
The three kinds of graph is bar graph, line graph, and pie graph. bar graph is used to compare two or more things. A line graph is used to show changes over time. A pie graph is used to show proportions.
Most graphs: Pie charts, bar graphs, histograms, scatter graphs can all be used.
bar graphs are used to compare different data. a line graph is used to see the changes over a period of time of a specific data. a circle graph is used to represent a part to a whole relationship.
Bar graphs, pie charts, and even line graphs can all be used to compare. I personally like to use Bar graphs when showing numbers.
bar graphs are for measuring points of data.
circle graphs add up to 100% , bar and line graphs don't
Bar graphs are used to display countable data that are grouped in categories.
well...not sure if you know this but bar graphs already ARE bar graphs, the good news is you don't have to transform them... so half your work is already done XD!
Error bars are often used on graphs to show statistical comparisons.
Both bar graphs and picture graphs show statistics (data) in a visual (graphic) form.
