SimpleTimeline is a Vaadin component for presenting data points on a horizontal line. It consists of two classes: - __SimpleTimeline__ Timeline element itself containing the items. - __SimpleTimelineItem__ A single item on the timeline that contains the text, HTML. Basic usage is as follows: ``` final SimpleTimeline t = new SimpleTimeline("Release schedule"); t.add(10, "Planning").addClassNames(SimpleTimelineItem.STYLE_SECONDARY,SimpleTimelineItem.VARIANT_DASHED); t.add(20, -1, "Brainstorming"); t.add(40, "More planning").addClassNames(SimpleTimelineItem.STYLE_PRIMARY); t.add(70, 2, "Scrum").addClassNames(SimpleTimelineItem.STYLE_PRIMARY, SimpleTimelineItem.VARIANT_FILLED); t.add(95, 2, "Deadline: 31.12.2022").addClassNames(SimpleTimelineItem.VARIANT_FILLED, SimpleTimelineItem.STYLE_ERROR); t.setBreaks(25,50,75); t.addClickListener(e -> Notification.show(e.getItem().getText())); add(t); ``` Which creates the following timeline:  This component is based on [@parttio/simple-timeline](https://www.npmjs.com/package/@parttio/simple-timeline)
