Medical Knowledge Graph

It is rare to find a medical graph database (knowledge graph) in medicine, as it is one of the last industries to embrace this new technology. Others, such as Netflix and Walmart, leverage graphs. In addition, it is really rare to find a demo or live knowledge graph (KS) that you can mine (query). I first asked Gemini 2.5 Pro if it could create a KS and it answered in the affirmative so I asked it to create a small medical KS. 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 which it found and used. Because this is prototyping software, it only uploaded 49 patients (nodes) and multiple texts (edges). I worked with Gemini to add more features: filtering by heart disease status, chest pain types, risk factors and demographics. It also added an "Ask Gemini" option to question the database and an export CSV button to download answers. Lastly, it created visualization and correlations buttons at the top.
