Exploring the Berlin subway system through the lens of graph databases using Memgraph Lab offers a fascinating insight into how complex networks are formed and analyzed. The analogy between the intricacies of subway connections and graph database relationships highlights the latter's role in organizing and enriching data with properties that provide context and depth. The blog post guides readers through the process of acquiring data on Berlin's subway stations and lines, preparing it in CSV format, and importing it into Memgraph using Docker. It details how to visualize these connections and perform various queries to uncover insights, demonstrate the flexibility of graph databases, and enhance understanding through graph styling. By using this approach, the blog emphasizes the power and potential of graph databases in data analysis and visualization, encouraging further exploration beyond the Berlin subway system.
