I haven’t posted in a while, but there are lots of projects in the pipeline. Watch this space.
In the meantime, something I created while researching a story idea (I was curious about whether immigration to Canada from the United States had risen since the housing crash – it hasn’t) and updating myself on non-map visualization tools (Tableau Public is expensive*, ManyEyes is hopelessly unstable, the new Google Charts seems to be the way to go, but not for graphs in KML, for which you need the old Google Charts).
In any case, here are totals of new permanent residents in Canada from the U.S., taken from here and topped up with 2010 numbers provided by Citizenship and Immigration:
What I take from this is that 21st-century immigration to this country from the U.S. has been much more political than economic – it starts to rise more or less after the invasion of Iraq, rises steadily after Bush’s second inauguration, and starts to fall after the 2008 election.
* Chad Skelton points out that I’ve mixed up two versions of Tableau – this needs another look.
I produced a news-driven map yesterday of traffic death rates across the world (seen below). Producing a world-scale overlay isn’t that hard, given the KML, but the Mercator projection creates radical distortion toward the poles. Google Maps was originally intended as a driving aid, and wasn’t intended for this sort of thing.
