[Maps] Dynamic style by document age #39219
Description
Describe the feature:
Allow dynamic styling based on time fields relative to the selected date range for the visualization.
Describe a specific use case for the feature:
Imagine looking at live flight data positions over a period of time (say 1 hour). You could have several documents on the map showing the recorded positions. It would be nice to have a way to style these (color and/or symbol size) by the age of the @timestamp relative to the selected time range. So an older position (upper left, in the screenshot) might be a lighter shade of red than a newer position (lower right).
