How to best import a US Map Schematic?

[المشرف العام]

I would like to use the following wiki US Map schematic as a background to my map work. (http://en.wikipedia.org/wiki/File:Blank_US_Map.svg)It is a .svg file, and GeoReferencer is unable to import it.

1. I convert it to it to a .tiff through cloudconvert.com
2. I successfully import to GeoReferencer
3. I pick corresponding coordinates to situate my map, and use NAD83 as reference
4. Import in QGIS

=> PROBLEM: The map I have is distorted on QGIS (flattened)

What am I doing wrong?Should import in georeference in .svg ? (IF so what plugin to install since it is unable to import). Should I reference more coordinates ? (>10)Is there a setting I am missing? Am I using the wrong map?

I imagine many have had to import US map schematics in their QGIS, and face the similar challenge.

Thank you for your help
