Dot Plot: A Potential Alternative to Bar Plot
Bar plots are extremely useful for visualizing categorical variables against a continuous value. But when you have many categories to depict, they can get too dense to interpret.
In a bar plot with many bars, we’re often not paying attention to the individual bar lengths. Instead, we mostly consider the individual endpoints that denote the total value.
A Dot plot can be a better choice in such cases. They are like scatter plots but with one categorical and one continuous axis.
Compared to a bar plot, they are less cluttered and offer better comprehension. This is especially true in cases where we have many categories and/or multiple categorical columns to depict in a plot.
