问题
I am trying to get the uk's regions map, http://en.wikipedia.org/wiki/Regions_of_England, on GeoJSON format to use it on a web visits map on a website. Is there any place where you can get the data for different countries on GeoJSON format?

You can download the UK administrative boundaries from: https://www.ordnancesurvey.co.uk/opendatadownload/products.html
Scroll down the page until you see Boundary-Line.
You'll need to convert the shape files to geojson with a GIS tool. Here's a step-by-step tutorial:

The shape files supplied by the Ordinance Survey have different levels of detail. It sounds like you'd just need to convert the european_region_region.shp shape file.
ogr2ogr -f GeoJSON european_region_region.json european_region_region.shp
EDIT: don't forget to convert from Northing/Easting to Lat/Long if you want to work with Leaflet, Google Maps, etc
ogr2ogr -t_srs WGS84 -f GeoJSON european_region_region.json european_region_region.shp
The Ordinance Survey have a licensing policy that you'll need to comply with:

There's a useful github repository containing GeoJSON boundary data for UK, converted from ONS shapefiles https://github.com/martinjc/UK-GeoJSON
- Local Authority Districts (LAD)
- European Electoral Regions (EER)
- Westminster Parliamentary Constituencies (WPC)
- Electoral Wards
- Eurostat boundaries (NUTS level 1 & 2) for England, Scotland and Wales
- Statistical areas (super output etc.) used by ONS
Northern Ireland is the exception to these due to the strict licensing of the government agency "public" information.

I can't tell whether you're looking for country-level or subcountry-level boundaries. If it's the former, then:
Some of the examples for d3.js use a GeoJSON file that contains all the countries in the world. You can find it here: https://github.com/mbostock/d3/blob/master/examples/data/world-countries.json.
D3.js is also an excellent framework for actually rendering this data in svg, so if you haven't already, you might wanna look into it. For example: http://bl.ocks.org/2206590.

If you just want GeoJson files of UK boundaries (includes NI) you should just use - http://mapit.mysociety.org
Northern Ireland LGD (Council) boundaries - http://mapit.mysociety.org/areas/LGD.html
