I wish it was in color, or at least not white on black, of all things. Designers never seem to care much for accessibility.
In the current state, it is simply a poster, that works somewhat zoomed in, but zooming out and getting an overview is hindered by the small headlines and the lack of color.
Edit: on most browsers colors can be inverted, and there is a navigational element below the map
Well, one could include links between sections.
