+
+ <p>Flot has support for simple background decorations such as
+ lines and rectangles. They can be useful for marking up certain
+ areas. You can easily add any HTML you need with standard DOM
+ manipulation, e.g. for labels. For drawing custom shapes there is
+ also direct access to the canvas.</p>
