add lat and long lines?

[atmccann]

hey Mark,

DataMaps is awesome, thanks so much for building. Was looking to either add or bring back latitude and longitude lines that Mike Bostock usually includes with d3.geo http://bl.ocks.org/mbostock/3682698 -- was looking for a way to add them in datamaps.all.js but just kept breaking things. Is this an easy addition?

let me know, thanks!

Would it work to do something like this?:

   var map = new Datamap({
        scope: 'world',
        element: document.getElementById('container1'),
        done: function(datamap) {
          var graticule = d3.geo.graticule();
          datamap.svg.append("path")
            .datum(graticule)
            .attr("class", "graticule")
            .attr("d", datamap.path);
        },
       geographyConfig: {...}

yeah! except strangely the right-most longitude line doesn't render -- what gives? thanks for the quick fix though!

No problem!

And I have no idea why the right-most line doesn't show up. Just took a look - strange!

I'm going to close this issue since for the most part it's solved - but if you figure out why the line doesn't appear please leave a comment for future reference!

For that projection, it looks like Bostock just draws a sphere over the country to handle that issue

ha, good catch!
