If a country has a none-numerical value it returns NaN and then breaks styling for the rest of the countries.

It would be great to have an "how to" showing the steps what to do to add other maps.

Having this would make it much easier to contribute more maps or even more detailed maps (e.g. counties of a [federal] state - in OSM it would be admin_level=6)

Hi. Great project. Was working on adding a map and received the following error in browser console locally:

app.bundle.js:61248 Uncaught (in promise) TypeError: Cannot read property 'feature' of undefined(…)
(anonymous function) @ app.bundle.js:61248

Which points to this:

var topoJSONFeatures = _topojson2.default.feature(topoJSONData, topoJSONData.objects[mapType]).features;

Any idea what could be causing this?

Hello,

I am trying to use your sample project. After running the npm install and start commands I load localhost:3030. When I go to the editor page and click a map, nothing happens. Only two buttons show up: "Save SVG" and "Save PNG," but I don't see anything about uploading data.

Please, could you add Ukraine?

I get an empty site of your map-project, in my browser console i get the following error:

In which directory i have to copy the devtools (https://facebook.github.io/react/downloads.html) an which version i have to use?

Thanks for this great project!!!!

Taiwan Province is Chinese territory. But i can't see it on my map.

Hey @caspg, great tool! Thought I'd help out by pointing you to the official Vermont boundaries.
