Hi Nick, We don't have any direct support for heatmaps in Google Charts. However, it is similar to a stacked column chart, with bar.gap = 0. You'd have to specify the color of each cell since it wouldn't do that itself. We also don't have any colorbar available independent of the few charts that support it.
Another option is to use the Graph3d charts documented here: http://almende.github.io/chap-links-library/js/graph3d/doc/ These use the Google Charts data structures and API for setting up the datatable and options. Using the 3D surface plot, turn off the perspective, and rotate the view until it is on top of the z axis and you get a heatmap.
