When plotting categorical data, a bar chart is preferred because it effectively represents and compares different categories. Each category is displayed as a separate bar, allowing for easy visual comparison of their frequencies or counts. The height or length of each bar corresponds to the value of the category it represents, making it straightforward to see which categories are higher or lower in terms of frequency.

Bar charts are particularly useful when dealing with categorical data as they can clearly show the differences between different categories. This distinction is beneficial for analysis, as one can quickly ascertain where the majority or minority lies among the categories being examined.

While pie charts can also represent categorical data, they are generally more effective for showing proportions and may not provide as clear a comparison between categories as a bar chart does. Line graphs are typically used for continuous data to show changes over time, and scatterplots are best suited for displaying the relationship between two numerical variables, making them inappropriate for categorical data. Thus, the bar chart stands out as the ideal choice for visualizing and comparing different categories.
