Sources hedge on the significance and other aspects:
"oldest map found in China",
"oldest map with clearly marked distances",
"oldest extant Chinese map",
"oldest number-bearing map in the world".
But we've seen other claims of oldest map as much as 14,000 years
Another color dot distribution map from the NYTimes.
(Here.) This one maps census data on race at a county level
with dots placed (randomly) within the counties.
People per Dot changes with scale, and seems often to leave
empty space. Some of the county borders standout even when not drawn.
Robinson (Elements of Cartography, 1969) and Mackay
("Dotting the Dot Map" in Surveying and Mapping v9 pp3-10 1969)
wrote about dot size and value to get "coalescence"
and a visually appealing map.
This interactive map updates but draws upon such writing.

Hawaii 2012 Primary Election Mashup.
Point symbols using hue
rather than value to indicate ranges of a quantitative variable
for spatially extensive units may make sense if one considers
these as qualitative differences at polling places.
I think that the "turnout" percentage is of registered voters
rather than of eligible voters. Precinct variation in population
(vote) is not shown.
Kickstarter project for... Food, an Altas . Interesting way
to put together an atlas. Personnally, I think the guerrilla
cartography moniker is a bit strange. Drawing on a war metaphor
rather than one grounded in writing, informing, or educating,
while at the same time not indicating what is being fought for
or against seems a red herring. It also seems to signal a more
confrontational than useful take. Perhaps I need to see who
these folks are. Someone might want to see
whether this is a good kickstarter marketing strategy.
The Alaska State Ferry
I think this shows in (almost?) real-time where the vessels are.
The plate carree projection is a bit of a distraction but easy to
use in a mashup. The ship symbols sizes stay constant;
at smaller scales ("zoomed out") they are monsterously large and
at large scales they are tiny. The wake makes them look like
speed boats. Pointing at the vessels or the terminals gives
identifying text. The ferry trip from Bellingham to Juneau or Haines
is worth doing.
Some election mapping comments in an email from D. R. Fraser Taylor:
Re: [CCA-list] Nuanced map view of the US Elections
From: Fraser Taylor
Choropleth maps are probably one of the worst ways of showing US
election results.This visualisation is better but although much
more accurate it still has problems in terms of how the uninformed
user may perceive it. The granularity of the date is a distinct advantage.

Interactive map of The Rolling Stones' live show history.
I am not sure why the cartographer chose the projection(s?) that
are used, would like to have seen time and the sequence more easily
(which show was first? which last? how much time between shows?),
and are straight lines on this projection realistic (i.e., do you
think 1989's Steel Wheels tour really went like that?).

Here's (another) one on the consequences of bad data, via the BBC.

Jenni Sparks - hand drawn map.
I'm not sure what to call this type of symbology.
The texture results from hand drawing landmark features in orthographic
projection, (keeping major roads open?), integrating neighborhood
names, and using color to set off parks and water --- all to fill
the planimetric map. An interesting effect. I have not tried
to test the map simplification, and displacements of location and scale
of the features that are drawn. Analyzing them might make a good term project.

Nadeau. The 'mouse over' to retrieve statistical reports for
individual metropolitan areas is straightforward and common
enough, but note the "Plot" vs "Map" toggle and the movement of dots

That seems interesting. Does it work? What limitations would

Here's a dot map that shows one person per dot.

Here's another set of maps and commentary from MapBrief dealing
with 'first impressions' of maps. On the LA election map, I'm
wondering how, if it is one dot per voter, not about privacy but
about how many pixels it takes to display the map, or how few
voters it takes to elect a mayor there. Does the map fit on
screen if each voter gets even a single pixel?
