New Election Chartograms


The major winner inwards the concluding Great Britain 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 inwards previous elections. A Field Guide to Red as well as Blue America is like to a traditional tiled grid map, except dynamic bar charts accept been used instead of colored grids. At the opportunity 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 showtime fourth dimension that private grids accept been used to visualize historical election data. For example, afterward the Scottish Election inwards May, The Guardian used Sankey diagrams inwards a tiled grid map of Scotland to present the historical percent of votes yesteryear each political political party over previous elections inwards each electoral district.


Esri has too 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 inwards a give away of dissimilar ways.

My favorite persuasion inwards this tiled grid map is the Waffle Grid, which presents the historical election information inwards each state alongside a serial of pocket-size colored squares. Each foursquare is colored ruby or bluish to present how the state voted inwards previous States elections.

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

I accept a feeling that nosotros mightiness travel seeing quite a few of these types of tiled grid maps or chartograms inwards the adjacent half dozen months. If you lot desire to do an interactive version of this type of map as well as thence it mightiness travel a expert thought to start honing your d3.js skills as well as practise adding an SVG overlay pane to Leaflet maps.
