[OpenLayers-Users] please help to understand loading of existing geojson layers

[Jerome Freyre]

Hi,

They use a file called world_borders.js
This file contains a geoJSON with the world borders but also information
about statistics.

1. When the main file is loaded, they create a new map with options
2. They add a google layer to the map.
3. They create a new style and context
4. They create a vector layer with the precedent style and a geoJSON parser. 
5. They add the geojson to the parser and the parse is passed to the layer.
6. Finally, they add a control used for the select_feature event.

The style and the context are used to define the color of the country

Hope this will be useful,
Jérome
