Interactive Maps with Clustered Points/Markers

What’s this?

Maps can look messy with too many markers, affecting user experience and usability. To tackle this, amCharts 5: Maps – starting with version 5.5.6 – introduces a ClusteredPointSeries.

This feature neatly groups closely packed markers into a single “group” marker, simplifying the interface. It also handles clustering and unclustering automatically when zooming in on the map.

How to enable it?

If you already have a MapChart with a MapPointSeries set up, you’re almost there. To enable clustering, all you need is:

1. Make sure you’re running version 5.5.6 or later.
2. Change the type of your series to ClusteredPointSeries.
3. Define how your group bullet looks like.
4. Enjoy!

If you don’t yet have an amCharts-driven interactive map, now is a good time to create one 😉.
