+jQuery Sparklines
+=================
+
+This jQuery plugin makes it easy to generate a number of different types
+of sparklines directly in the browser, using online a line of two of HTML 
+and Javascript.
+
+The plugin has no dependencies other than jQuery and works with all modern 
+browsers and also Internet Explorer 6 and later (excanvas is not required
+for IE support).
+
+See the [jQuery Sparkline project page](http://omnipotent.net/jquery.sparkline/)
+for live examples and documentation.
