What is Google Map Chart?
- A Google Map Chart uses Google Maps API to display Map.
- Data values are displayed as markers on the map. Data values may be coordinates (lat-long pairs) or actual addresses.
- The map will be scaled accordingly so that it includes all the identified points.
Chart Type:
| S.No. | Chart Type / Description |
|---|---|
| 1 | Basic Map Basic Google Map |
| 2 | Map using Latitude/Longitude Map having locations specified using Latitude and Longitude |
| 3 | Customizing markers Customized Markers in Map |
Named Locations:
- You can identify the places to put markers by name, as shown below in this map of the top ten countries by population.
- When the user selects one of the markers, a tooltip with the name and population of the country is displayed, because we used the showInfoWindow option.
- Also, when the user hovers over one of the markers for a short while, a 'title' tip will show up with the same info, because we used the showTooltip option. Here's the full HTML:
