View this notebook in your browser by running a web server in this folder. For
example:
~~~sh
python -m SimpleHTTPServer
~~~
Or, use the [Observable Runtime](https://github.com/observablehq/runtime) to
import this module directly into your application. To npm install:
~~~sh
npm install @observablehq/runtime@4
npm install https://api.observablehq.com/d/5899e123023fd122.tgz?v=3
~~~
Then, import your notebook and the runtime as:
~~~js
import {Runtime, Inspector} from "@observablehq/runtime";
import define from "@pbogden/hello-leaflet-run-elsewhere";
~~~
To log the value of the cell named “foo”:
~~~js
const runtime = new Runtime();
const main = runtime.module(define);
main.value("foo").then(value => console.log(value));
