144            Odometer charts can be used to provide an indication of a particular value. For example you could easily use them to
145            represent values for a control panel that shows information about a server. Odometer charts indicating how much disk
146            space is used for example, would be more visual than a simple number.

149        <p>
150            The green, yellow and red areas are configurable, allowing you to add some level of urgency into your figures
151            (as are the colors). The
152            figures are also configurable, so it can go from 0-10, or from 0-100.
