Hey @RavindraNitwal,
TigerGraph Developer comes with GraphStudio included. There you can get the data in a graph way of showing it.
GraphStudio can also be used to write queries:

To present the data in the way you saw in the Graph Gurus 20 webinar, you will need an application (Node.js, Python, Java) for fetching and data processing using TigerGraph RESTAPI interface:
https://docs.tigergraph.com/dev/restpp-api/introduction-restpp
TigerGraph response is in JSON format.
The best starting point would be our G101:
