This one is just hosed because, I think, the data he had is different than the data I have. not just the values but the layout. some things are not numbers and I can't seem to coorce them unless I want to spend all day on it and I really don't. We'll just chalk it up to this one not being complete and call it that.

// Uncaught (in promise) TypeError: d.properties.2020.replace is not a function

//sizeScale .range is all kinds of hosed //console.log(radiusValue); // // == // d => d.properties['2020'] // (above that): const radiusValue = d => d.properties['2020']; // so I think that has something to do with it. Maybe an update in js?
