Timelines and Visual Histories

How can you show the details of a history visually? Time provides one obvious dimension. What else can you show to tell the story? Most timeline charts use a 2D representation, time x {place or theme}. Some are more successful in integrating additional dimensions.

This page is an annotated visual gallery of some timeline designs from their origin to today. Although time is one-dimensional, telling some story of history visually is much more complex, and it is quite instructive to see together how different graphic designers have aproached this problem.

PNNL: InfoViz – Technologies – ThemeRiver™

The ThemeRiver™ visualization helps users identify time-related patterns, trends, and relationships across a large collection of documents. The themes in the collection are represented by a “river” that flows left to right through time. The river widens or narrows to depict changes in the collective strength of selected themes in the underlying documents. Individual themes are represented as colored “currents” flowing within the river. The theme currents narrow or widen to indicate changes in individual theme strength at any point in time.
