I came across this interesting map of 1888 horsedrawn streetcars in Washington DC:
Not entirely difference from the location accurate version of the modern subway map:
Of course, a more accurate comparison is probably to a modern bus map. but they are so busy:
DC is scheduled to re-introduce streetcars in 2013/14, starting with a small run along H Street SE.
Alphadesigner continues to take satirical mapping to a new level, with several dozen maps of stereotypes, from many different perspectives, updated regularly.
I had no idea there was a red-head enclave in Russia. (further discussion)
A clever animation of how the bikes move around throughout the day. You have to watch it on slow to really get a feeling of what’s going on.
Meteorite fireballs witnessed from 1913. I’m not sure what is gained by putting this on a map. Also, since this is just eyewitness accounts, it suffers from population density bias.
There really aren’t many differences between the two current proposals, which were designed to incorporate the new Silver Line to Dulles airport. As mentioned in the WashPost comments, the only major flaw I see is using the same color for the background beltway and DC boundary as for the Silver Line.
To be honest, I still prefer a lot of the options that Cameron Booth proposed in his 2010 reworking:
This has been making the rounds. I like that they used alpha shading to show variations. And it’s pop, not soda.
Immigration has always been a tough issue to deal with.
The chart reminds me of this John Stewart bit on immigration and “Traditional America”:
This has been making the rounds. Based on 150,000 geocoded tweets from June 2012 to April 2013, filtered 1st by use of word, and then manually whether it was used in a negative or derogatory fashion.
Obviously this suffers from selection bias as it only includes people who bother to tweet, and those who aren’t ashamed to do it publicly. There’s also the usual population density distortion (last map below), which would be compounded by cell phone coverage out west. So, basically, this is another pretty visualization of social media meta data that doesn’t really mean much of anything. To be honest I’m surprised they only found 150,000 hateful tweets in 11 months. (The author’s FAQ is an interest read)
