title: Vector Labels
shortdesc: Example of GeoJSON features with labels.
docs: >
  This example showcases a number of options that can be set on text styles.
  When "Text/Wrap" is chosen (for example for the line features), the label is
  wrapped by inserting the character `\n`, which will create a multi-line
  label. The "Open Sans" web font will be loaded on demand, to show dynamic font
  loading.
