  Nice visualizations, thank you!

  I was thinking of building an interactive visualization of mountain prominence, by progressing down the contour lines till the current contour line encircles a peak that is taller than the one that I started with.

  I think Quadtrees will come handy in this visualization, if a precomputed list of all the peaks were available.

    In Vivaldi, point insertion seems to be x-offset to the left or right of the mouse click.
