Update D3 to the current version

Summary:
Ref T13279. Old D3 seems perfectly fine, but most of the good references seem to have been written by people who update D3 more than once every 10 years (???).

This requires some minor API changes, see next diff.

Test Plan: See next diff.

+
+## Installing
+
+If you use npm, `npm install d3`. Otherwise, download the [latest release](https://github.com/d3/d3/releases/latest). The released bundle supports anonymous AMD, CommonJS, and vanilla environments. You can load directly from [d3js.org](https://d3js.org), [CDNJS](https://cdnjs.com/libraries/d3), or [unpkg](https://unpkg.com/d3/). For example:
+
+```html
+<script src="https://d3js.org/d3.v5.js"></script>
+```
+
+For the minified version:
+
+```html
+<script src="https://d3js.org/d3.v5.min.js"></script>
+```
+
+You can also use the standalone D3 microlibraries. For example, [d3-selection](https://github.com/d3/d3-selection):
+
+```html
+<script src="https://d3js.org/d3-selection.v1.js"></script>
+```
+
+D3 is written using [ES2015 modules](http://www.2ality.com/2014/09/es6-modules-final.html). Create a [custom bundle using Rollup](https://bl.ocks.org/mbostock/bb09af4c39c79cffcde4), Webpack, or your preferred bundler. To import D3 into an ES2015 application, either import specific symbols from specific D3 modules:
+
+```js
+import {scaleLinear} from "d3-scale";
+```
+
+Or import everything into a namespace (here, `d3`):
+
+```js
+import * as d3 from "d3";
+```
+
+In Node:
+
+```js
+var d3 = require("d3");
+```
+
+You can also require individual modules and combine them into a `d3` object using [Object.assign](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign):
+
+```js
+var d3 = Object.assign({}, require("d3-format"), require("d3-geo"), require("d3-geo-projection"));
+```
