Note

This is an early beta version so don’t expect too much from it. To experience the knowledge graph, click the textbox labelled Search and select items and type the keyword “takeover”. Then, select the “Account Takeover” item. This is because the network graph contains very content at this point of its development. From there, the Knowledge Graph UI will display a number edges and nodes. Click on the nodes to load and explore the graph from there. Use the #knowledge-graph Slack channel to provide feedbacks and contribute to the project.
