xkcd visualizations

I'm a big fan of Randall Monroe's web comic xkcd.  I find its nerdy humour particularly amusing.  Randall often employs visualization in xkcd, so I've combed through the xkcd archives and picked out some of my favourite examples.

Movie Narrative Charts


Days of the Week

Colour
Randall conducted a survey of 222,550 users (sessions) for the names they ascribed to over five million colours.  From a subset of the results he built the map below showing the most popular names for the fully-saturated colours.


Self-Description
Three clever self-referential charts.


Some rare examples of good infographics:

Gravity Wells


Lakes and Oceans


Fuck Grapefruit
The outlier that is grapefruit.


Exoplanets

The remaining examples I've simply grouped by type.

Line Charts


Bar Charts


Pie Charts


Flow Charts


Venn Diagrams
