title: Interactive uk counties map in python dash application
body: <p>I have spent ages trying to figure out a way of putting an interactive UK Counties map on a Python Dash app.</p>
  <p>The map will show locations of tweets from the twitter developer api that I have in an sqlite database.</p>
  <p>I've tried using Folium, but attempting to load counties from a massive GeoJSON file is a mess, and takes ages,and I can only find a GeoJSON file for English counties. I also need Scotland and Northern Ireland. I don't really want the map to be able to move, but I realise I might have to accept that as a consequence of zooming in or out. I just want the user to be able to click on a county and show twitter data in a separate part of the webpage. I would also like to put markers in the relevant county for tweets in my sqlite database that have location data. The user could then click on the marker and reveal the text of the tweet.</p>
  <p>I know amcharts have an uk-counties.svg chart, but:
  a) I can't fathom out how to embed this on a Dash webpage, and
  b) if I do get it on a webpage, would I then be able to show location data, and if so, then how?</p>
  <p>I've looked at MapBox, openstreetmap, and google maps, but they all seem overly complicated for what I'm trying to do.</p>
  <p>Any help/suggestions would be hugely appreciated.</p>
