How to add responsive & interactive world map on your website easily with Google GeoChart tool
A couple of months ago, my friend showed me a website featuring an interactive world map displaying the organization’s locations all over the world as well as their number of employees in each location. After a little of digging, I’ve found that it’s not hard to replicate such interactive world map on my site. At its core, the world map is powered by Google visualization tool, and all you need to do is do re-use their code and a little bit of tinkering to customize the map fit your purpose.
Note that this is not using the image map/hotspot — when you add a static image (of the map) and slice it into different region then add the mouseover code to create the effect.
