Research direction

Start by locating the TimeSliderChoropleth implementation and its generated map-layer styling, then inspect how stroke colour, width, opacity, and dashed lines are currently set. Done should be a documented way to control or remove those styles, with coverage showing the resulting map configuration.

Description

enhancement

Hi,

I am having issues with trying to change the line colour/width/opacity/removing dashed line for the TimeSliderChoropleth, is this possible or would it be a possible feature add please? The white dashed lines I am getting are meaning you cannot see the data on the map.

Thanks (and thanks for all the development on this, its great),
Amy
