Geo Chart in Google Charts
Geo Chart
A geo chart is a map of a country, a continent, or a region. It is identified in these three ways:-
- The region mode colors whole regions, such as countries, provinces, or states.
- The markers mode uses circles to designate regions that are scaled according to a value that you specify.
- The text mode labels the regions with identifiers.
Steps for adding Google Geo Charts to your Website:-
- To use Google Geo Chart on your website, add a link to the charts loader.
- After this, add a div with a unique id. Then, we have to load Google Graph API.
- Load the Visualization API with the desired package name. In our case, it is "geochart".
- Set a callback function.
- The visualization API is:- google.charts.load('current', {'packages':['geochart']})
- The callback function will be:- google.charts.setOnLoadCallback(draw_my_chart)
