WIP - Update map projections use robinson

[mrchrisadams]

this isn't ready for a merging in, but I can't see a way to set up an issue on the main repo to ask this question

Hi there,

I wanted to start work on making a version of the internet health report which uses a different projection then the Mercator one. Specifically I'd like to try replacing the Mercator projection with the Robinson projection - one that tends to be better for showing the true sizes of countries on a map, and doesn't make greenland seem to overwhelmingly huge.

You can see more about the differences in the projection - there's even a game to show how much it distorts the size of countries:

The way I think I'd do this would be switch the line where the geoMercator projection, is specified here:

https://github.com/mozilla/internet-health-report/blob/master/src/javascripts/modules/visualizations/Choropleth.js#L66

    const countries = topojson.feature(this.shapeData, this.shapeData.objects[`countries`]);
    const projection = d3.geoMercator()
      .fitSize([this.width, this.height], countries);
    const path = d3.geoPath()
      .projection(projection);

…and instead use the geoRobinson projection

https://github.com/d3/d3-geo-projection/#geoRobinson

However, I can't seem to get the app to run when I call npm run as directed in the readme.

Here's what I'm getting when I try starting to develop locally on my macbook laptop running npm 5.5.1, and node v8.5.0

My guess is that npm is loading the latest version of a library that has a breaking change, based on the TypeError: require.extensions.hasOwnProperty is not a function message I'm seeing.

Is it possible to share a list of the known good libraries, so I can add a something like a lockfile, to freeze the set of dependencies for any future work?

Thanks for sharing the source code to make forking it possible, and seeing how it works in the first place 👍
