What type of chart uses rectangles to show the data?

The type of chart that uses rectangles to represent data is called a bar chart. In a bar chart, rectangular bars are used to show the frequency or value of different categories, with the length or height of each bar corresponding to the quantity it represents. Another related chart is the histogram, which displays the distribution of numerical data using adjacent rectangles. Both types of charts are effective for visualizing comparisons between different groups or categories.
