I need assistance developing a knowledge graph with causal explanations, utilizing Vector Cypher Retriever and Neo4j, based on my custom data. I have a custom database table (csv) with all kind of information: timestamps, target (price data), embeddings from event extraction, sentiments and much more. I want to create a knowledge graph to visualize the relationships and dependencies between the features (focus on sentiments and event embeddings) and make the event embeddings and price (target) explainable -> why is there a price up movement -> because of event x,y,z Please use python, neo4j
