circles-alpha¶

Description¶

• node and relation defaults are enabled

• node_one checks if relation_one is present

• relation_one checks if node_one and node_two are present (first circle)

• node_two checks if node_one is present (second circle)

• if node_one is absent, then also node_two and relation_one are absent

• since the solution is optimized towards minimal numbers of nodes, the expected template is empty
