Then, in the final step, we count the number of observations in each bin and plot a bar for each bin. Then, the x-axis is divided up into sections, which we call "bins." There might be a bin from 0 to 20, then another bin from 20 to 40, and so on. Taller the bar higher the data falls in that bin. As defined earlier, a plot of a histogram uses its bin edges on the x-axis and the corresponding frequencies on the y-axis. So you need to add a new column to your data frame like this.
