I hate this graphic. Should we consider the 3rd dimension as well? I mean, the "thickness" of the barrel is much bigger behind e.g. UAE than Oman. From the numbers it seems we shouldn't.
But the boundary follows the arc on the top and bottom, so it's definetily projected to the half surface of a cilynder, but the voronoi lines are straight, but they should curve just like the top and bottom.
I would be legitimately impressed if the data is scaled based on the volume of the implied cylindrical section defined by that surface border, if only because that's a pretty annoying calculation to make.
Also, what about the back side of the barrel? Who is producing that oil?
This is no better than mercator projection for maps, hated by all and every cartographer who isn’t a navigator. You are my friend, now.
Data is
beautifulimpossible to interpretData is awful... What was wrong with bar charts?
Bar charts for long lists of nations are ...long. And pretty hard to read. I'm not sure this is the best solution, but it works OK.
They can group them, drill down, there are many way to make them readable. That's the actual work of data visualization: simplify something complex to convey a message, leading the reader to the relevant data that support the message, letting them understand it.
Here nothing is readable with the exception of the big polygons, and data are absolutely unclear even when the polygon is visible
That's an interesting type of visualization. Is there a name for this type?
It looks kinda like a Voronoi diagram but as far as I know those don't really do specified areas/volumes for a cell.
