Size of the circles in the Kibana Tile map visualization


In Kibana we have a visualization called Tile map which has has several options to customize, such as map type.

My question is about one of this types: Shaded Circle Markers which is basically about changing colors based on value.

Documentation says:

Displays the markers with different shades based on the metric aggregation’s value.

and that's correct, but I don't understand why some bubbles are bigger than others.

I assume that this may be due to the distortion caused by Mercator projection, which which is well presented by Tissot's indicatrix, but I didn't find any source which confirming my hypothesis.

Could you confirm my suspicion or explain in other way this behavior?

Solution

  • I've got an answer from Elastic Team Member who confirmed my suspiction. This distortion is caused by Mercator projection.
