Create a program that takes a file of statistics as input, computes how many of the numbers have x as a leading digit for all x 1-9, and then plots a bar graph showing the relative frequency of each of the digits when they lead off a number. The output of your program should look something like this:
File: "sunspot_data.txt" frequency of the lead digit
