use python pls
Previously, an X was used to represent every integer value. However, we don't have space to represent large values using the approach (e.g., it would be unreadable if the values were in the hundreds or thousands). Therefore, we need to scale the bars so that each X represents a larger quantity We will display the bars as percentages, where the largest value in the data set is treated as 100%. The height of the other bars will...
