<h1>Populations of Western English-Speaking Countries</h1>
<p><b>Implementation:</b> Specify population of each country
as a HTML5 data attribute of each element containing the country's name,
and using the "dataset" attribute to retrieve the values.</p>
<p>When I originally created this page, it didn't work.</p>
<p>But now it does work, and it's probably the most "correct" way
to annotate HTML elements with data.</p>
<table id="populationTable">
<tr><td id="australia" data-population="20000000">Australia</td></tr>
<tr><td id="canada" data-population="33000000">Canada</td></tr>
<tr><td id="ireland" data-population="4000000">Ireland</td></tr>
<tr><td id="nz" data-population="4000000">New Zealand</td></tr>
<tr><td id="uk" data-population="61000000">United Kingdom</td></tr>
<tr><td id="usa" data-population="298000000">United States of America</td></tr>
