EasyTimeline by Erik Zachte is an extension for creating graphical
timelines with clickable links. WikiHiero by Guillaume 'Aoineko' Blanchard
is for rendering hieroglyphs. Both are now enabled on all Wikimedia wikis.
As per our earlier extension syntax vote, EasyTimeline uses the <timeline>
syntax, WikiHiero uses the <hiero> syntax.

To my knowledge, MediaWiki is the only wiki software which supports such
functionality. It should make our wikis interesting even in the highest
academic circles.
Although EasyTimeline can generate SVG output, only PNG output is
currently supported. In the future, we hope to offer SVG as a user
preference.
