What type of graph uses labelled vertical columns to represent different values?

The type of graph that uses labelled vertical columns to represent different values is a column graph. In a column graph, each column corresponds to a specific category or group, and the height of the column reflects the value or frequency associated with that category. This visual representation makes it easy to compare different items or datasets at a glance, as the varied heights of the columns highlight differences in value.

While a bar graph is similar and often used interchangeably, it typically features horizontal bars instead of vertical columns. In contrast, line graphs utilize points connected by lines to display trends over time, and pie charts represent data as proportional segments of a circle, making them unsuitable for depicting values as vertical columns. Therefore, the identification of a column graph as the correct answer is based on its specific characteristic of using vertical columns to represent different values clearly and effectively.
