Interesting. The 'country' borders aren't working the way you and I thought they would have. I guess Oregon doesn't really have a 'border' with another country so it's not given a border with the ocean. You can clearly see this behavior with the state of Texas: border with Mexico, but not with the Gulf of Mexico. This might be something Ian & Jake would want to take a look at:
The work-around is of course to add all the states to your viz and then assign white to all zero values and washout Urban Maps altogether.
Easy answer: Use the "Gray" map style. It should get you close to where you want to be.
Hard answer: If we have a country outline for the US rendered you can hack your TMS file and add it as a layer. I'd have to look if we do.
Can you start by trying the Gray map style and seeing if you like it?
I tried the Gray map, but I would still have to use the "Base Layer" to get the coastal borders to appear, and I was trying to avoid having any gray shading in states that have zero funding, so that it does not look like they have the "least amount," but that it is actually zero (the white contrast is better to show this).
I am going to also try what Shawn suggested and just add in placeholders of "$0" in funding for the states I don't have any data for to see if the coastal borders will appear then (as white).
Jake -- if you do find a country outline layer rendered for the US, it would be great if you could send that my way!
