The City Intelligence Unit at the London Datastore has released a genuinely interesting visualization of London Commuting Flows. The visualization uses an interactive cartogram to exhibit where the residents inward each London borough move to piece of job inside London.
The cartogram repesents every London borough every bit a small-scale square. Each of these small-scale squares is a mini choropleth map showing where inward London the local residents commute to work. In other words the visualization consists of small-scale multiple maps organized geographically. You tin forcefulness out genuinely mouse-over the smallest borough squares inside each private borough foursquare to stance the let out of commuters who commute betwixt the 2 boroughs (which makes the cartogram audio a lot to a greater extent than complicated to go than it genuinely is).
I similar this visualization a lot. As a static ikon it would hold out an effective visualization on its ain of the spatial blueprint of commuting inward London (the bulk of commuters from each borough tend to piece of job inward fundamental London or inward neighboring boroughs). As an interactive visualization, however, it allows y'all to drill downwardly as well as explore the commuting flows of private boroughs as well as stance how many residents from each borough move to every other borough inward the capital.
The London Commuting Flows visualization was created using After the Flood's London Squared D3 module. This module allows y'all to easily create your ain similar looking interactive cartograms of London.
