GraphRAGs- The way forward!

I am Data Engineer and have an experience of 8 years. For last 1.5 year i had participated in various hackathons to learn AI, RAGs and Agents. I had used Neo 4j 6 years ago and glad that Graph RAGs are a place where i can connect my experience. I have taken 3 courses from Neo 4j academy to implement KGs with LLM. Unfortunately, i am unable to make it into a useful output. Anyone here who has implemented Graph RAGs, i want to seek your guidance.
