In Question 3 you were asked to guess the distribution of newly completed homes across the four main districts in the city. Building on the circular layout of the chart in the question—in which the districts were arranged around the circle according to their true position in the city—here I generated a “compass” visualization that allows you to observe recent trends in housing data from a high-level spatial perspective. 

The charts have two layers: they grey areas follow the principles of radar charts and portray the most recent data; the spirals are animated radial line charts that depict the evolution of each value, from 2012 to the most recent data available. You can visualize datasets about newly completed homes (apartments or other types of dwelling) but also on home prices and rent, two related topics you already encountered in the first two questions. Click on each of the charts to select it and observe it in detail.
