Sharing a recent research byproduct: rounded 1M-pop gridded #cartogram based on 2025 #population, totaling 342 units. It's not easy to balance recognizable state shapes with accurate adjacencies. In #LEGO form, I also added cities in 1M-pop increments. Which of the two styles do you prefer? 🟨🟡

Dit plaatje is geografisch correct, maar demografisch volstrekt misleidend. De Hond weet dat een dergelijke kaart een vertekend beeld geeft als het om electorale steun gaat. Zijn keuze om geen #cartogram (gevormd naar bevolkingsaantal) te gebruiken maakt dat mensen als Fabiënne hun hart vasthouden.
Isodemographic Map of Canada. by University of British Columbia, Canada Department of Fisheries and Forestry, Canada Policy Research and Coordination Branch. Published in 1971. Shows census division boundaries, census metropolitan areas, selected census major urban areas, selected incorporated cities, and provincial and international boundaries Based on Dominion Bureau of Statistics 1966 census of Canada. Areal scale: one square inch represents 60,000 people. Legend in English and French Indexed for census divisions The extreme spatial contrasts in population density in Canada, partly due to the advanced stage of urbanization, make a conventional map an unsuitable base to use in the presentation and analysis of many population characteristics. A map of Canada has therefore been devised in which the areas occupied by census units are proportional to their population. In addition, separate maps of the twelve largest urban centres have been devised which show census tracts in the same manner but at a larger scale. The necessary transformation of the area and shape of census units was achieved mechanically by means of physical models of Canada and the individual cities in which the populations of the units were represented by appropriate numbers of 1/8” diameter steel ball bearings. The final output, termed an isodemographic map, is a graphical refinement of the physical models to which boundary detail and some topographic features have been added to aid the user. An Isodemographic map is a type of cartogram in which the size of each area (e.g., country, province, city) is proportional to its population. (Synonym: density-equalizing map) A cartogram is a map in which the geometry of regions is distorted in order to convey the information of an alternate variable. The region area will be inflated or deflated according to its numeric value.

Evident in the pin holes & damaged edges this map was in heavy use through the years.

Now please make it a #CARTOGRAM because a lot of that big red space barely has any people in it.
How does that look with a #CARTOGRAM that illustrates numbers of voters?

Here's a first🐍hack. The objective function only includes distance from original position. Optimization is mixed-linear programming. I'd like to include a "clustering" term to punish gaps, but its hard to encode. #gis #cartogram #datavis @driven-by-data.net
Cartogram of 299 German election districts
For the German election we wanted to use a cartogram of German election districts but didn't find anything good, so we created our own. Here's a little nerd thread how the final algorithm worked 🤓 🧵 #gis #cartogram #election #datavis #cartography

Your own previous version makes much more sense. This data really wants to be a #choropleth #heatmap or a #cartogram.

Thank you for using a #Cartogram This is a much more clear and honest way to report numbers of people rather than acres of land. 🙏

I’ve not seen as much fun with cartography in years as people are enjoying @mapbox #cartogram. Seriously though, some amazing inspiration.
