About the Bar Chart
A bar chart uses rectangular bars to represent values for different categories. The length of each bar is proportional to the value it represents, making it easy to compare quantities at a glance.
Bar charts work for any audience — they are intuitive, fast to read, and well-understood. They excel when you have a small-to-medium number of categories (2–15) and want to show absolute values.
Start your axis at zero, sort bars by value when order doesn't have inherent meaning, and keep labels short and horizontal. Avoid 3D effects and decorative fills.
