GistMap is a service for publishing maps, with no backend infrastructure, just static files and public services. It works by downloading a configuration file from Gist, then fetching geojson/topojson from any CORS-enabled URL, and tabular data files from Google Spreadsheet, then rendering them in the browser. Here are some examples:

• Top 1000 Romanian cities, by population (source)
• Birth rate by county (source)
• Test with many small polygons (communes of Romania) (source)

Creating a map

• Prepare a Features file and a Data file

• Create a Gist with a Configuration file named map.json

• Take the ID of the Gist and create a URL in the following format to render the map in a browser: http://mgax.github.io/gistmap/?gist={id_of_gist}. You can embed this in another web page using an iframe:

  <iframe src="http://mgax.github.io/gistmap/?gist={id_of_gist}"
        width="400" height="215" frameborder="0" scrolling="no"
          marginheight="0" marginwidth="0"></iframe>
