This plugin for <a href="http://www.flotcharts.org">Flot charts</a>
downsamples data before rendering the chart.
The purpose is to try retain the visual characteristics of the
original line using considerably fewer data points.<br />
The algorithm (called <i>Largest-Triangle-Three-Buckets</i>) used in this plugin is described in a
Master's thesis (see <a href="http://hdl.handle.net/1946/15343">hdl.handle.net/1946/15343</a>) in Computer Science by Sveinn Steinarsson
at the <a href="http://english.hi.is/">University of Iceland</a>.
The topic of the thesis is how to <i>downsample time series for visual representation</i>
and was initially suggested by <a href="http://datamarket.com/">DataMarket</a>.
JavaScript optimization was done with the help of <a href="https://github.com/borgar">Borgar Þorsteinsson</a>.
