Overview
jqPlot is a plotting and charting plugin for the jQuery Javascript framework. jqPlot produces beautiful line, bar and pie charts with many features. jqPlot's Strongest Feature is its Pluggability! Computation and drawing of lines, axes, shadows even the grid itself is handled by pluggable "renderers". Not only are the plot elements customizable, plugins can expand functionality of the plot too!
