I am convinced by Greyblades map, it is rather compelling and does contain lots of nice colours, it has links and everything.
Though I am slightly confused as to why such things as a chip pan catching fire are included in the seeminlgy random "crime" "statistics".

I say random , though of course it is not random , someone appears to have just trawled the newspapers, twitter and facebook, found anything with foriegners in Germany mentioned and added it to a list of "crimes"
