		<p>Example of loading data dynamically with AJAX. Percentage change in GDP (source: <a href="http://epp.eurostat.ec.europa.eu/tgm/table.do?tab=table&init=1&plugin=1&language=en&pcode=tsieb020">Eurostat</a>). Click the buttons below:</p>

		<p>The data is fetched over HTTP, in this case directly from text files. Usually the URL would point to some web server handler (e.g. a PHP page or Java/.NET/Python/Ruby on Rails handler) that extracts it from a database and serializes it to JSON.</p>

		<p>
			<button class="fetchSeries">First dataset</button>
			[ <a href="data-eu-gdp-growth.json">see data</a> ]
			<span></span>
		</p>

		<p>
			<button class="fetchSeries">Second dataset</button>
			[ <a href="data-japan-gdp-growth.json">see data</a> ]
			<span></span>
		</p>

		<p>
			<button class="fetchSeries">Third dataset</button>
			[ <a href="data-usa-gdp-growth.json">see data</a> ]
			<span></span>
		</p>

		<p>If you combine AJAX with setTimeout, you can poll the server for new data.</p>

		<p>
			<button class="dataUpdate">Poll for data</button>
