It's possible to drag and zoom map.
Based on
Projection Transitions by Mike Bostock and
Map Projection Transitions by Jason Davies.
Using a hidden canvas to calculate if the "pixel" points are within a land polygon or not, and then the "pixels" are drawn as SVG rectangles. This gives me possibilites to initiate a "pixel" map
and then edit the DOM in any way I want after that like an ordinary SVG.
