<div class="textblock"><p>This is a header-only, generic, data analysis system that allows for creating performant generation of <em>Plots</em>. <em>Plots</em> contain <em>Values</em> and can make use of <em>Filters</em>. <em>Filters</em> can also depend of <em>Values</em>, and <em>Values</em> can depend on other <em>Values</em>. A <em>Dataset</em> is a generic object that contains a series of observations. The individual observations consist of a series of <em>Observed Values</em>. One can also define <em>Derived Values</em> which are calculated from <em>Observed Values</em> or other <em>Derived Values</em>. Care is taken automatically so <em>Derived Values</em> are calculated at most once per observation.</p>
