Display map boundaries more clear with deck.gl Charts

What is the problem or goal the end user is trying to solve or accomplish?

When using deck.gl Charts (for example, the Polygon Chart), map boundaries can be difficult to visualize.

How are they solving it currently?

There isn't a workaround at the moment - decreasing the Opacity of the Polygons might help but it's not very effective.

What is the recommended solution by the Customer?

Provide users the ability to increase the Opacity for the map boundaries.
