Geo Charts - Display Country-State-City Map

[ravi prakash]

Hi All,

I recently started using Geo Charts and it looks really great. I want to develop some thing like this,

First load the world map 

Click on a country in world map to load the particular country map - Now map must change to clicked country showing all states in clicked country

Click on a state in country map to load all cities/counties/regions in that state. - Now map must change to state showing all cities in the clicked state.

Please let me know how to achieve this using Geo Charts. 

Thanks,

Ravi

Hi Ravi,

The GeoChart doesn't have any city or county region maps. What you'd have to do is to switch the GeoChart to 'markers' mode when you want to display cities, and trust the geocoding to work correctly.

Effectively, you'll have to listen for the 'regionClick' event from the GeoChart, which will tell you which region was clicked. At that point, you would have to detect whether you need to display cities, and if so, switch to 'markers' mode and render your cities dataset.
