"Styles" within Layer Settings is where you can control how this layer's features look in this map.
NOTE: Access is restricted to Admins only
Select any color and opacity, and for points you can select the symbol that will represent the feature. You can also control if a label should display, with full control over what the label content should be.
Every layer will have at least one style - the default style. However, you are able to add as many additional styles (style overrides) that you would like, which will apply to features that match the field value that you set in the style override.
