📘 What is a Bar Chart?
A bar chart (or bar graph) is a type of chart that presents categorical data with rectangular bars where the height or length of each bar is proportional to the value it represents. Bar charts are ideal for comparing values across different categories or groups.
Unlike line graphs that show trends over continuous data, bar charts excel at displaying discrete data comparisons, making them perfect for visualizing survey results, sales by category, population distributions, and more.
