Plot the equation "y = 5 ** x" for the integer values between 1 and a million.

pay_it_forward.py

import math
from matplotlib import pyplot

figsize = (15, 5)
pyplot.figure(figsize=figsize)

pyplot.title('Paying it forward')

data = []
end = 1000000

for idx in range(end):
        data.append(math.log(5) * math.log(idx + 1))

pyplot.xlabel('Number of people receiving a gift')
pyplot.ylabel('Paying it forward cycles')


pyplot.plot(range(end), data)
pyplot.show()

A friend on facebook posted this status update :

"Who likes to get surprises in the mail or at work?! Everyone right? So PAYING IT FORWARD 2014 is something I will try. Here's how it works; The first 5 people to comment on this status will receive from me, some time in the next calendar year, a gift: perhaps a book, or a baked good, or a candle, music - a surprise! There will likely be no warning. The catch? Those same 5 people must make this offer in their FB status. That simple."

So I thought it would be interesting to graph the "paying it forward cycles"
