Seeking help with Voronoi map generation
I'm hoping somebody here can help me create a particular map. I'd like to build a weighted Voronoi map of North America, with the weights corresponding to each urban area's population. Or, put another way, I'd like to start with http://lpetrich.org/Science/GeometryDemo/GeometryDemo_GMap.html , input the urban areas listed at https://en.wikipedia.org/wiki/List_of_urban_areas_by_population , and then tweak how the map is produced so that if one metroplex has a population of 1,000,000 and another has 10,000,000, the border between them is about 90% of the way closer to the smaller city.
I'm trying to build a scifi setting to put a story in, and have certain suspicions about what such a map would look like, but would like to confirm my intuition. I'm running Fedora Linux, and don't mind compiling oddball software, I just don't know which packages I'd need to even try to generate this thing.
By any chance, anyone here already able to generate the final product with just a few mouse-clicks? :) If not, anyone have any advice on how to get started?
I'd like to see the resulting map - at least of that doesn't interfere with your plot. Or if a variant of same.
It turns out that in order to make this Voronoi library work, I have to reduce the cities' weights so much that they make effectively no difference to the overall figure. But if you'd like a map, then after toying a bit with https://en.wikipedia.org/wiki/File:MapofEmergingUSMegaregions.png and https://en.wikipedia.org/wiki/File:Ninenations.PNG , my un-weighted Voronoi map of North America looks a little like http://www.datapacrat.com/temp/NorAm%20Regions.jpg . Needs some further tweaking, but might be food for thought. :)
