I tried cloning the repo and copying the code of the map colored each country a different shade of blue. I get two TypeErrors when inspect the page that says "Loading..." on Chrome an go to the Console output.

mappa.js:643 Uncaught TypeError: _staticMap[this.provider] is not a constructor
    at Mappa.staticMap (mappa.js:643)

thanks for the catch! A wrong map provider was set in that example. I just updated it to reflect the changes

That seemed to remove the issue I was having before, but now I'm running into a different issue, but it seems something more about my setup. Any guidance to get the visualization to display?


mappa.js:756 You requested an image with a height of 800px. Google Maps Static API max height value is 640px. For larger images, change the scale to 2 and keep the height between 1-640px. i.e: if you want an image 800x800px, set the width and height to 400x400 and the scale to 2.

I just edited the size of the image and that got rid of the first part. I'm going to try hosting it somewhere else to see if that fixes the second part.

I seem to have fixed it by hosting it on a web server so that it has access to HTTP something or other. Thank you for the help!

Yes, you need to set up a server for that. Check out this tutorial for setting up a local server.
