Adding new countries

[michalskop]

It is really nice.
Is it possible and if so, is there any documentation how to add/create a custom tilegram?
E.g. for Czech republic, for Europe, etc.?
What would be the needed sources?

Currently we don't have documentation. But you can see examples of adding other regions in some existing PRs. Check out #83 or #85 for references. Happy to add in PRs for new regions if you come up with any.

@nthitz I've looked at #85 but I'm not sure how the maps/ireland/Irish_Constituencies.topo.json is created. I know there's no GUI to work around with, but can you explain that part, since the other file changes look fairly simple, but I'm struggling with this one. Ideally I'd like to offer a map for Bulgaria based on the previous population data and update it when the new one comes out next year :)

@roshavagarga the topojson maps typically come from third party sources. something like https://github.com/techslides/D3-Maps/blob/master/data/world/country/Bulgaria.topo.json might work for Bulgaria
