The knowledge graph populates the extra panels you often see in Google search results that contain relevant information to the search query, often trying to answer your query immediately without having to click on a different website.

The knowledge graph acts more like a mind map that understands how different entities relate to each other, so when you search for someone like Zendaya, you may see extra information about the media she has starred in, the awards she has won, trivia about her and her social media.

Alternatively, you could search for something short form, such as “time in India”, and immediately get the Indian timezone and current time. This data comes from various sources, notably Wikipedia and other trusted databases.”

An example of Google's knowledge graph, showing the actor Zendaya. Pictures of her, her social media and information from her Wikipedia page are all shown in Google's search results.
