- <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>
