This page provides a graphic overview of the events in the history of data visualization that we call "milestones." These milestones are shown below in the the form of an interactive timeline. The timeline is divided into two vertical sections. You can drag each section left or right to see milestones of different time periods. You can also click one of the links at the bottom of the timeline to jump to a particular epoch.
Each of the milestone's in the timeline can be clicked to reveal its summary that includes both a link to its full details and a category to which it belongs. The category can also be clicked to initiate a search of other milestone's based on that category.
