What is the difference (or interconnections) between Link Charts in ArcGIS Pro and ArcGIS Knowledge? One seems to run in Pro another is service\server based. Is the capability the same? Trying to figure out the product differences, use cases, applications, etc. Thanks.
@COSPNWGuy - Thanks for the question. You are right about the key distinction you mentioned. The default localized Link Charts in ArcGIS Pro can be thought of as Feature Link Charts, or Map-Based Link Charts. The Link Charts in ArcGIS Pro and ArcGIS AllSource, based on ArcGIS Knowledge Investigations, can be considered Investigation Based Link Charts. I've summarized some key distinctions below.
To your ultimate question about when to use which one, that will boil down to how you want to manage the relevant data (more centrally or locally), what kind of analyses you are doing (do you need robust selection and exploration tools), who is doing the analyses (are multiple analysts contributing), and how big and complex is your data. We think of Feature Link Charts as a simple starter tool for simple use cases to start visualizing links without needing to do as much prep to your data. But the limitations will likely leave you wanting more features that come with a knowledge graph based approach.

Knowledge Graph Link Charts
There are other differences in the selection tools, and kinds of link and graph analytics that can be done on each as well, as summarized in the graph below.
