Hi sdssds,
You have three choices to use specific map. First, check Highcharts map collection to find a map:
http://code.highcharts.com/mapdata/. Another one, you can find a SVG map and convert it with online converter. Here you can find exmple of pacific-centered world map converted from SVG file:
http://www.highcharts.com/studies/map-f ... _World.svg. Lastly, you can try to create map on your own from scratch using an SVG editor. All required information regarding this approach can be found here:
http://www.highcharts.com/docs/maps/custom-maps.
Example:
