How to use: drag a box on the PCA plot, or click any area (shift-click for several), and the same areas light up in every view. Double-click to clear. The region menu filters everything, and the variable menu colours the first map by any of the 20 Census variables. Scroll to zoom and drag to pan on the t-SNE, catch-up and model-fit plots; double-click resets them. Hover for exact values. Grey areas on the change map are councils merged between 2019 and 2021, which have no like-for-like 2021 figure.
