The upper half shows a summary of the statistics on the left and charts to investigate the distribution and relationships of scores on the right. The lower half is a table with the individual traces which we can use to debug individual samples.\n",

-    "When looking at the statistics, we can see that the accuracy of our RAG pipeline is 22% as measured by `answer_matches_target_llm_grader`. Though when checking the quality of our retrieval step (`context_query_relevancy`), we can see that our retrival step is fetching relevant information in only 27% of all samples. As shown in the GIF, we investigate the relationship between the two and see the two scores have 95% agreement. This confirms that the retrieval step is a major bottleneck for our RAG pipeline. So, now it's your turn to improve the retrieval step!\n",
