I want Obsidian to read the Daily Notes and follow the links, but at the same time, I want to make them invisible or transparent when I view the graph.
You could also put them in a folder and set that folder as “ignored files” (settings → files and links). That’s what I do with processed daily notes, templates, test files, tutorials and other things I don’t want to show in the graph.
Of course, if the wish is to see the links in graph view, then my solution isn’t the right one. If only wishing to see the links in the files, then it works.
