Medical Knowledge Graph

It is rare to find a graph database (knowledge graph) (KG) used in medicine, as it is one of the last industries to embrace this new way to store data instead of a relational database. Many others, such as Netflix and Walmart, leverage knowledge graphs. In addition, it is really rare to find a demo or live knowledge graph (KG) that you can mine (query). Many people need to learn a new programming language, such as Cipher, to do this.

First, I asked Gemini 2.5 Pro if it could create a KG, and it answered in the affirmative, so I asked it to create a small medical KG. It did that successfully, so I then asked it to use real cardiac data. On its own it said, "I will use data from the Cleveland Clinic heart study." It added the filters you see on the left, and it added shading to suggest those with no heart disease belonged in the greenish area and those with heart disease belonged in the pink zone. There is also clustering by age. It also added an "Ask Gemini" option to query the database and an export CSV button to download answers. Lastly, it created visualization and correlation buttons at the top of the app.
