Definition
Bar Graph
 A chart that uses either horizontal or vertical bars to show comparisons among categories. One axis of the chart shows the specific categories being compared, and the other axis represents a discrete value.
 Used to visualize the distribution of categorical data.
 Also called bar chart.
Tips for creating bar graphs:
 Use a horizontal bar graph rather than a vertical one when:
 the category labels are too long to fit neatly on the xaxis.
 there are more than 10 categories, because there is more room to label the categories.
