Screenshot from an interactive applet that visualises around 27000 series from the collection of the National Archives of Australia. The graph is a kind of stacked histogram; each series is represented as a horizontal line correpsonding to its date span. Series are sorted according to span, then stacked into a pile. Colour is also derived from year span - blue=long, red=short. The interactive simply highlights series whose span includes any given year. Blogged here.
