We use ECharts in our open source BI tool (Evidence) and it's a great library. Has helped us build a declarative syntax for viz which can be version controlled (https://evidence.dev)
We're fans of Obsidian! DataView looks cool - love the ability to define the tables in code inline in the markdown. That's similar to how we inline DuckDB WASM SQL queries in markdown: https://docs.evidence.dev/core-concepts/queries/
Evidence looks cool, and I evaluated sometime back. The docs says the pages are all pre-rendered for all possible combinations. Is that the case still? If so, if I have a date filter, is it going to pre-render all possible dates?
We recently changed our architecture to include interactivity without having to pre-render all combinations. Pages are still pre-rendered with their initial content, but each Evidence app now ships with filter components and an in-browser DuckDB instance so you can build interactive apps. We call this Universal SQL - if you're interested, we wrote up our rationale for doing this here: https://evidence.dev/blog/why-we-built-usql/
Reminds me Obsidian DataView but with charts https://github.com/blacksmithgu/obsidian-dataview
This whole ideas to have data, visualisations and knowledge base in one private offline place is very appealing
