Tensorflow.js Graph Object Detection

Im currently building a web-app that uses tensorflow to scan graph data and turn the data into a visualisation, at the minute the app can only detect a small number of objects based on the coco-ssd trained model (Person, phone, bottle) and I’m struggling with 1) finding other tensorflow models that I can implement to improve what can be detected. 2) tensorflow models that can scan for objects and data within a graph and 3) how to add another model into my code without breaking what already works. I’m very new to using tensorflow and machine learning but below is the code for the web-app that requires the tensorflow model.
