How to delete regions from your projection map
You can remove a region from a visualization by deleting the corresponding row in the Regions data tab. In the below example, we started off with the blueprint of London and deleted all boroughs but Hackney.
- Locate the rows with the region or regions you would like to delete and delete them
- Switch to the Preview tab and make sure the bounds are set to "Auto"
If you are deleting regions from a map of the US, the projection will probably still be set to "Albers USA" and your regions will display relative to the whole of the US (see example below). Therefore, make sure and switch to a different projection, for example "Equirectangular", and select your bounds to be "Auto".
