Functionality to add Maps?

I’m trying to add a map to a post that I created in d3, but I’m unable to get the map to show up. I’m wondering if this plugin has functionality for maps or if it’s something I’m doing wrong in the plugin. I’ve uploaded the map geo data (which was json) as a txt file, so I don’t know if that’s potentially the issue?
