Cartograms for the 2019 Canadian Federal Election

In 2015 I worked on making hexmap cartograms of predictions and then the preliminary results of the Canadian federal election.

And @ksituan made a square grid cartogram superimposed on a traditional projection map for the 2015 elections. https://www.deviantart.com/strathconabooster/art/2015-Canadian-Election-Cartogram-769814396

This got a bit out of hand but I need to also cite the beautiful page by @severo_fr on grid cartogrammes which includes a reference to @attaboy essay from 2011. https://observablehq.com/@severo/grid-cartograms

In 2019 2019: I used @olihawkins d3-hexjson library and the hexjson data format developed by @ODILeeds to redo my map. The library includes a very nice online editor, and the hexjson format is the right way to do this. I added boundary functions to the library.

Here are predictions of @qc_125 338Canada seat-by-seat predictions 19 October. This doesn’t exaggerate the impact of large sparsely pop. ridings compared to small but densely pop ridings. Some ridings are mixed up.

I wasn’t the only one working on such presentations (outside of media outlets, of course).

@OryxMaps updated a hexagon cartogram map of results as they came in. https://twitter.com/OryxMaps/status/1186503005379665921

@attaboy prepared a very nice implementation with a hexagon cartogram at electoralcartogram.ca

Similarly, @ksituan promises to update his square grid cartogram superimposed on traditional projection map in the near future with #elxn43 results.
