=============

1. multi-dimensional arrays
---------------------------
Initialize a 2-dimensional array with the following values:

2, 3, 5, 7, 11
1, 3, 5, 7, 9
2, 4, 6, 8, 10

Write a perl program to iterate over the array.
Find the minimum of the maximum of each row.


2. Super Bowl
-------------
superbowl.html contains information about past super bowl games. 
write a perl program to process the file, and extract the data
into a 2D array. Finally, iterate over the 2D-array and print
out the values.


3. Google Charts
----------------
Using your code from part 2, calculate the the number of
superbowl appearances for each team.

Then, use the Google Charts Api to create a pie chart showing
the teams with 6 or more Super Bowl appearances.

The following code shows an example of how to create a url
for a pie chart. You will modify the $data and $labels
variables:


use LWP::Simple;

# build the url for a pie chart with 4 data sets:
$addr = "http://chart.apis.google.com/chart?";
$size = "&chs=200x100";
$type = "&cht=p";
$colors = "&chco=FFB61D|76A4FB|80C65A|FF5E3E";
$data = "&chd=t:1,2,3,4";
$labels = "&chl=one|two|three|for";

$url = $addr.$size.$type.$colors.$data.$labels;

$content = get($url);
die("could not get webpage!") unless defined $content;

# write the content to the file:
open(OUT, ">image.png");
binmode(OUT);
print OUT $content;
close(OUT);
