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 bubles 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?
