* no more elements prop - v-model instead! * Instead of passing an object map to components just pass in an array of strings as nodeTypes/edgeTypes object * the string name will either be resolved to a dynamic component with :is="type" or a slot with the type-name * update all examples Signed-off-by: Braks <78412429+bcakmakoglu@users.noreply.github.com>
