bubblegrid helps you see your data when a plain scatterplot would be overplotted. To do that, it aggregates points within a hexagonal grid, then shows the point count as the bubble size. It also shows the intensity (e.g. gene expression) via color. The intensity / gene expression is averaged within bins.
