Kenneth Field and Craig Williams put together <a href=\"https:\/\/twitter.com\/kennethfield\/status\/1187093377231314947\">a series of maps showing the Canadian election results<\/a> in a number of different ways: we have a <a href=\"https:\/\/www.axismaps.com\/guide\/multivariate\/value-by-alpha\/\">value-by-alpha map<\/a>, a <a href=\"http:\/\/wiki.gis.com\/wiki\/index.php\/Proportional_symbol_map\">proportional symbol<\/a> map, and two kinds of <a href=\"http:\/\/wiki.gis.com\/wiki\/index.php\/Dot_density_map\">dot density maps<\/a>: one showing the winners, one showing all votes per constituency. (One dot equals 100 votes; the dots are spread evenly across constituencies, even when people aren\u2019t. You can\u2019t have everything.) And it\u2019s on the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Lambert_conformal_conic_projection\">Lambert<\/a>, not the Mercator.<\/p>\n<p>Speaking of the Mercator. <a href=\"http:\/\/googlemapsmania.blogspot.com\/2019\/10\/2019-canadian-election-maps.html\">Maps Mania\u2019s roundup of Canadian election results maps<\/a> notes that the Canadian media\u2019s interactive maps (e.g. <a href=\"https:\/\/newsinteractives.cbc.ca\/elections\/federal\/2019\/results\/\">CBC<\/a>, <a href=\"https:\/\/globalnews.ca\/news\/6023150\/live-canada-election-results-2019-real-time-results-in-the-federal-election\/\">Global<\/a>, <a href=\"https:\/\/www.theglobeandmail.com\/politics\/election2019\/results\/\"><em>Globe and Mail<\/em><\/a>) invariably resorted to <a href=\"https:\/\/en.wikipedia.org\/wiki\/Web_Mercator_projection\">Web Mercator<\/a>, largely because of the mapping platform used. (In-house infographics team? Don\u2019t be ridiculous.) Web Mercator is singularly bad for Canadian election maps, because <a href=\"https:\/\/en.wikipedia.org\/wiki\/Nunavut_(electoral_district)\">Nunavut<\/a>: it\u2019s the largest electoral district by area (1.9 million km<sup>2<\/sup>) and the smallest by population (31,906). It\u2019s enough of a distortion on the Lambert: Mercator makes it worse.<\/p>\n<p>As for cartograms, <a href=\"https:\/\/twitter.com\/kennethfield\/status\/1187515902922645505\">Ken hated<\/a> the one I posted <a href=\"https:\/\/www.maproomblog.com\/2019\/10\/a-cartogram-of-canadas-election-results\/\">last night<\/a>; Keir points to Luke Andrews\u2019s <a href=\"https:\/\/electoralcartogram.ca\">Electoral Cartogram of Canada<\/a>, which is a bit nicer, and uses only one hexagon per riding instead of seven. Keir also points to <a href=\"https:\/\/observablehq.com\/@mountainmath\/canadian-election-bubble-animiation\">this animation<\/a> that shifts between a geographical map and a cartogram.
