Bar charts are primarily used for displaying and comparing the frequency, count, or other measures (e.g., mean) for different categories or groups. While they can indeed be oriented horizontally or vertically and show frequencies or relative frequencies, they are not exclusively used for numerical data in the sense of continuous data types (like heights, weights, or ages). They are most commonly used for categorical data (like survey responses, colors, or countries).
