I have a vector layer which is geoJSON file containing school points and their attributes,to visualize this i defined cluster and show circle which size is based on the number of features it contains. Whenever the zoom level reaches individual schools, i need to display symbol of school.
In style, i can define the size of cluster using the pointRadius property, and show icon using the externalGraphic property. i need to use both at once i.e use rendering as circle if cluster is more than one and render as icon in individual feautures.
How can i do this?
