The ecoregions are loaded from a GeoJSON file. Information about features is
retrieved using the layer's `getFeatures()` method on hover and click. For
vector layers, this function resolves with an array of only the topmost
feature. It uses a very efficient hit detection algorithm, at the cost of
feature. It uses an efficient hit detection algorithm, at the cost of
accuracy. For pixel exact hit detection, when performance is not a concern,
use the map's `getFeaturesAtPixel()` or `forEachFeatureAtPixel()` methods.
