How does a bar chart differ from a histogram in Tableau?

The choice highlighting that a bar chart categorizes data while a histogram shows numerical data distributions is accurate in distinguishing the two visualizations.

A bar chart is used to represent categorical data. Each bar represents a distinct category or group and displays its value, making it useful for comparing different categories at a glance. The separation between bars emphasizes that each represents a discrete category, allowing viewers to easily identify relationships among the categories.

On the other hand, a histogram is specifically designed for displaying the distribution of a continuous variable. It groups numerical data into bins, showing how many observations fall into each range of values. This makes it effective for illustrating the underlying frequency distribution of the data, such as identifying normality, skewness, or the presence of outliers within the dataset.

The other options do not accurately capture the fundamental differences between bar charts and histograms. For instance, the concept of trends does not directly apply in the same way to either type of chart, and the orientation of the charts can vary depending on the design choices made in Tableau. Additionally, both charts can effectively utilize colors to enhance visual communication; thus, color efficiency is not an inherent distinction between them.
