OK, playing around with different projections, scales and translations in d3 solved my problem. Since the default projection when using d3.geo.path() is albersUsa there was good reason to try some other projections. I suppose the problem could have been solved easier using the right EPSG specification when converting the shape file but these obscure numbers exceeded my knowledge.
So what I did in the end is simply using a mercator projection and bringing it into the svg-viewport with translate().
d3.json(
"http://localhost:8888/data/data.json",
function (json) {
//dimensions
var w = 2000;
var h = 2000;
var svg = d3.select("#chart").append("svg")
.attr("width", w)
.attr("height", h);
//create geo.path object, set the projection to merator bring it to the svg-viewport
var path = d3.geo.path()
.projection(d3.geo.mercator()
.scale(20000)
.translate([0, 3800]));
//draw svg lines of the boundries
svg.append("g")
.attr("class", "black")
.selectAll("path")
.data(json.features)
.enter()
.append("path")
.attr("d", path);
});
Here's a link to the shape files i used and the resulting geoJSON. To simplify the shapefiles, which I got from GADM, I used mapshaper.
I would still be interested in a less laborious and more flexible solution. So if anyone has an Idea, thanks in advance! But for the moment I'm happy I can recognize the 16 Bundesländer of Germany!

You need to convert the Shapefile to DXF and then it can be read by Corel Draw
you can convert the shapefile to dxf using http://www.guthcad.com.au/arcv2cad.htm
Corel DESIGNER® Technical Suite X5 is the best option for DXF support
