Design Patterns Identification & Visualization

Hello, i would like to ask, if you could help me with my project. The project theme is Identification and Visualization of design paterns. My approach with half-finished code is graph-based. Im using node.js with jdtls with lsp request and helper functions which adds details. Json from the code im putting inside neo4j graph db. where im cypher querying design paterns. The help i need from you is to find benchmark datasets for design paterns (probably P-mart), fix my code/cypher querries bcs i think right know its not correct. Im trying to identify singleton/strategy/decorator/adapter/factory method. In my sampleproject it identifies just fine, even in refactoringguru github examples. But when i tried junitv3.7 for example, it wasnt really accurate. The thing is, i dont know if from the client.js im getting every information correct way, and if i have all the neccessary info i need. Because if not, then my cypher querries would never work. But since its my first time working with something like this, im little confused and lost. Thats why i tried to find help. I hope i kinda explained what am doing, and i would like to ask what price this might take, and how long it will take.
Thank you for answer and have a nice day.
