FiveThirtyEight has a nifty interactive map, showing different ways to draw US House boundaries.
I would like it done mathematically, to create compact districts. But, since counties have to administer elections, I like the last one best, “Make districts compact while following county borders”.
—Show current district boundaries
—Gerrymander districts to favor Republicans
—Gerrymander districts to favor Democrats
—Match partisan breakdown of seats to electorate
—Promote highly competitive elections
—Maximize number of majority-minority districts
—Make district shapes compact (using an algorithm)
—Make districts compact while following county borders
