Visualization about distribution of futures #52

Hi, thanks for your great work! I am very interested in the future distribution visualization in figure 1, could you please tell me how to plot it?

Hello, to get this figure, I've generated different future trajectories by sampling a 100 times. Starting from a bird's-eye view image full of zeros, I then increment each cell whenever a trajectory passes through the cell. This image is then obtained by visualising the heatmap of the bird's-eye view cell counts.

If a trajectory is very likely, the cell count will be very high. Conversely, if a trajectory is very rare, it will have a low cell count.
