City Lens
Place a lens anywhere on the map and see how data is distributed in that area. Move it across the city to compare neighbourhoods, zoom in on specific districts, or use multiple lenses simultaneously to contrast different parts of the same dataset. Each lens aggregates the data points within its radius and displays the breakdown as a bar chart around the rim.
