In a chart, are features represented as columns or rows?

In many chart formats, particularly in typical data presentations like bar charts or column charts, features are often represented as columns. This format allows viewers to quickly assess the value or magnitude of each feature at a glance, as the height of the columns effectively conveys the data relationships. For instance, in a bar chart, each column correlates to a specific category (feature), and its height indicates the value associated with that category.

Choosing columns as the representation format is ideal for comparative analysis, as it visually distinguishes between the different features and their corresponding values. While some charts may indeed utilize rows (particularly in structures like tables), the question specifically highlights the representation style commonly found in many standard charting techniques, where features are effectively displayed vertically as columns.

In contrast, rows typically represent data attributes or individual records in a tabular format, and while some chart types may utilize rows, the standard convention in visual data representation leans more toward columns for feature comparison.
