Bar charts are specifically designed to display categorical data, which helps in comparing different groups or categories. They represent distinct categories along one axis, while the other axis shows the value corresponding to each category. Since time series data consists of observations recorded at specific time intervals and often demonstrates a continuous flow of data over that time, line graphs are typically the preferred choice for visualizing trends in such data. They reveal patterns or changes over time more effectively than bar charts, which may obscure the temporal relationships inherent in time series data. Thus, stating that bar charts can only be used for categorical data aligns with their intended purpose and effective application in data visualization.
