A vertical bar graph is a type of graph that visually displays data using vertical bars going up from the bottom. In a vertical bar graph, the lengths are proportional to the quantities they represent. Vertical bar graphs are typically utilized when one axis cannot have a numerical scale. A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. A Pareto chart is different from a vertical bar graph because the bars are positioned in order of decreasing height, with the tallest bar on the left.
