Main Improvements

Improve performance clustering on map view #1396

When configuring a map layer of point type, the number of points you can get on the map is limited. In order to improve this, we intend to improve the presentation method internally to improve the performance. First, we switched cluster operations to the server side for performance and expressive advantage. And then applied optimization techniques such as bbox filters for efficient server-side operations based on zoom levels.

Support multi-layer on map view widget #1107

From this version, now you can make multiple layers on your map chart! Display any measures what you want to describe on your map.
