Election Chartograms

The major winner inward the concluding United Kingdom of Great Britain as well as Northern Ireland full general election was the tiled grid map. My bet for this year's U.S. election is the 'chartogram'.

For instance this calendar week the Wall Street Journal has created an historical U.S. election map which represents each state equally a bar nautical chart showing the state winners inward previous elections. A Field Guide to Red as well as Blue America is similar to a traditional tiled grid map, except dynamic bar charts bring been used instead of colored grids. At the adventure of butchering the English linguistic communication language I'm going to shout out to this type of grid map equally a 'chartogram'.


This isn't the get-go fourth dimension that private grids bring been used to visualize historical election data. For example, later on the Scottish Election inward May, The Guardian used Sankey diagrams inward a tiled grid map of Scotland to demo the historical percent of votes past times each political political party over previous elections inward each electoral district.


Esri has likewise been experimenting alongside using dissimilar types of charts as well as graphs inside private tiled map grids to visualize U.S. election history data. US Election History is an interactive tiled grid map which visualizes the historical voting designing of each state inward a set out of dissimilar ways.

My favorite persuasion inward this tiled grid map is the Waffle Grid, which presents the historical election information inward each state alongside a serial of modest colored squares. Each foursquare is colored ruby or bluish to demo how the state voted inward previous USA elections.

The Wall Street Journal is showing similar historical election data, alone it is using bar charts rather than 'waffle grids'.

I bring a feeling that nosotros mightiness live on seeing quite a few of these types of tiled grid maps or chartograms inward the side past times side vi months. If you lot desire to do an interactive version of this type of map as well as hence it mightiness live on a practiced thought to start honing your d3.js skills as well as exercise adding an SVG overlay pane to Leaflet maps.
