New Yorker here to translate.

Manhattan is almsot all green except for a sliver on 5th Avenue near Central Park. That's the priciest area. Most of the rest of the borough is pretty pricey. even Harlem apartments are getting expensive, now that it's being gentrified.

Most of the red areas aren't particularly pricey and certainly aren't considered high class or exclusive.

The bright red area all the way at the bottom left is the South Shore of Staten Island.

I once met a woman who taught Art History at Staten Island College. She told me that many of her students had never made the trip into Manhattan to visit the Metropolitan Museum, one of the top museums in the world.

That really red area under the mouse cursor is... Borough Park? Super conservative Jewish area? Or maybe bensonhurst? I live here but am apparently bad at maps.

The lower the density of housing, the lower the favorability... Interesting

It's all the outskirts except for central Manhattan and surprisingly Williamsburg, Brooklyn, which I thought was part of the Commie Corridor. Flushing is expected considering many first generation Asians are conservative (read: racist) and prefer to vote for a white man.
