    <h1>Flot Examples</h1>

    <div id="placeholder" style="width:600px;height:300px"></div>

    <p>1000 kg. CO<sub>2</sub> emissions per year per capita for various countries (source: <a href="http://en.wikipedia.org/wiki/List_of_countries_by_carbon_dioxide_emissions_per_capita">Wikipedia</a>).</p>

    <p>Flot supports selections. You can enable
       rectangular selection
       or one-dimensional selection if the user should only be able to
       select on one axis. Try left-clicking and drag on the plot above
       where selection on the x axis is enabled.</p>

    <p>You selected: <span id="selection"></span></p>

    <p>The plot command returns a Plot object you can use to control
       the selection. Try clicking the buttons below.</p>

    <p><input id="clearSelection" type="button" value="Clear selection" />
       <input id="setSelection" type="button" value="Select year 1994" /></p>

    <p>Selections are really useful for zooming. Just replot the
       chart with min and max values for the axes set to the values
