• 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 x-axis.
  • there are more than 10 categories, because there is more room to label the categories.
