Note: I had to rename this add on from "VaadinDistributionBar" to "DistributionBar" to follow the Vaadin naming guidelines (this is NOT official Vaadin add on). Technically 0.3.2 is identical to old VaadinDistributionBar 0.3.1. My mistake, sorry. Distribution bar is simple UI component that can be used to present distribution between different groups (e.g. distribution of votes). Please check screenshot and online demo. Transitions are done with CSS3 and tested with Firefox, Webkit and Opera browsers. IE 8 and 9 are also supported, but transitions are simple not shown with these browsers (lacking CSS support). Transitions and look is done totally with CSS so you can easily modify the look of distribution bar.
