The Future Atlantes Part II

I recently posted "The Future Atlantes Part I" and promised a new installment. Well, here it is and it took a great deal of thinking and hair-pulling and teeth-gnashing:

The idea:

Make a 3D graph of the cities (x, y) with their population (z) shown as sticks scaled by 450,000 (the maximum population of the cities under 10 meter elevation was around 12,000,000). This way, it can easily show visual learners which parts of the world have the most people in danger of having to emigrate from their home place due to global warming (either with fair-warning or with a rough storm which inundates the whole place). This dilemma poses another question: how will all these displaced persons find a home or money (who wants a home stuck under the sea)?

My seemingly simple algorithm:

I'll start assuming you know what I did for Part I.
I made some extra rules of coordinates of cities to their corresponding populations. Then, I used the points of the cities under 10 meter elevation to be my x and y coordinates and the population to be my z coordinate (scaled down by 450,000). (This all had to be filtered as well against the not available data). Then, I graphed it with Graphics3D[].

A little more in-depth:

I created one module which took about 3 lines of code to convert a 2D point (the coordinates of a city) to a 3D line(which includes its scaled population and goes straight down: similar to the Filling option of ListPlot). That one module probably did the bulk of the work (well, with Map's help as well).

(Hopefully, I can show full functionality with a video on Wolfram Demonstrations or YouTube, as recommended by Dr. Choi).

Future:

Scale the populations not to a stick length but to a colored point or maybe colored tubes.
