Obsidian, for example, has a built-in renderer and a whole lot of plugins that can extent it. For instance, dataview plugin can query other notes and render result in place. So for example, you have a few notes with a tag "book-review". And in them you use YAML preamble to track rating you gave the book. Dataview can render you a list of books you reviewed and their ratings (even in star form), individual rows linking to the specific notes. Another example, built-in TeX rendering support, which makes it much easier to read math formulas. Likewise, built-in Mermaid for diagrams.
