 # brainglobe-heatmap
-Rendering anatomical heatmaps with brainrender and matplotlib.
+`brainglobe-heatmap` allows you to create heatmaps, mapping scalar values for each brain region (e.g., number of labelled cells in each region) to a color and creating beautiful visualizations in 2D (using [matplotlib](https://matplotlib.org/) or 3D (using [brainrender](https://brainglobe.info/documentation/brainrender/index.html)).
