Points

Points are seemingly the simplest type of shape, possessing only position and no other dimensions. MBStyle has a circle type that can be styled to represent a point.

Example points layer

The points layer used for the examples below contains name and population information for the major cities of a fictional country. For reference, the attribute table for the points in this layer is included below.

15 }

Details

There is one layer in this MBStyle, which is the simplest possible situation. The “version” must always be set to 8. Layers is required for any MBStyle as an array. “id” is required and is a unique name for that layer. For our examples we will be setting the “type” to “circle”.

Simple point with stroke

This example adds a stroke (or border) around the Simple point, with the stroke colored black and given a thickness of 2 pixels.

13         "circle-stroke-width": 2
14       }
15     }
16   ]
17 }

Details

This example is similar to the Simple point example. Lines 12-13 specify the stroke, with line 12 setting the color to black ('#000000') and line 13 setting the width to 2 pixels.
