⚠️ I am sorry this tool isn't working properly. Google has recently started charging for its Maps API, and I got billed >$1000 for people's use of this tool during August 2018. I can't afford this, so I have had to disable the billing for now. This is why you now see ugly warnings over the map. I am trying to work with Google to get this fixed without costing me lots of money, but I don't know if that will be possible. If you have any clever ideas, ping me on Twitter @obeattie.
