This is a fair criticism and from the feedback represents a fairly major missing functionality in the site. For what it's worth I only realised this might be a useful feature after I finished version 1. From my write up[0]: "Allow multiple trends on the same plot. It would be interesting to compare Kubernetes with Docker directly, or PyTorch with Tensorflow to get an idea of the relative trends in attention". Initially I built the front end to analyse a single term (recession) rather than for trend comparison but it would definitely be useful and I'll look at adding it.
