Left: The cluster graph. Edge opacity indicates the proportion of spots in the higher-resolution cluster that originate from the lower-resolution cluster. Right: Array plot. Pie charts show gene expression similarity between spatial regions and the cluster centroids. In both plots, expression profiles are projected into color space by PCA, so that similar clusters have similar colors
