+    <div id="placeholder" style="width:600px;height:300px;"></div>
+
+    <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>
+      <input class="fetchSeries" type="button" value="First dataset"> -
+      <a href="data-eu-gdp-growth.json">data</a> -
+      <span></span>
+    </p>
+
+    <p>
+      <input class="fetchSeries" type="button" value="Second dataset"> -
+      <a href="data-japan-gdp-growth.json">data</a> -
+      <span></span>
+    </p>
+
+    <p>
+      <input class="fetchSeries" type="button" value="Third dataset"> -
+      <a href="data-usa-gdp-growth.json">data</a> -
+      <span></span>
+    </p>
+
+    <p>If you combine AJAX with setTimeout, you can poll the server
+       for new data.</p>
+
+    <p>
+      <input class="dataUpdate" type="button" value="Poll for data">
+    </p>
