Modifying a scatterplot
In the previous exercise, we created a scatter plot to show Freddy Frequentist's cell phone data.
In this exercise, we've done some magic so that the plot will appear over a map of our town. If we just plot the data as we did before, we won't be able to see the map or pick out the areas with the most points. We can fix this by changing the colors, markers, and transparency of the scatter plot.
As before, the matplotlib.pyplot module has been imported under the alias plt, and the cellphone data is in the DataFrame cellphone.
