Hi,
I found myself using a lot of advanced tables in Obsidian recently for summarising my expenses as well as progress in some of my projects. Because of that I came found myself using a lot of mermaid graphs for some data visualisation, but was naturally hindered, since mermaid graphs (except for pie chart) don’t really work well with numerical data. Of course I could just do graphs in excel, which I did, but still I though it would be cool to do it all within Obsidian itself.
With chart.js it would be possible to use a mermaid-ish syntax to create a wide array of graphs and charts suitable for data visualisation and it’s integration with markdown is already possible in Jekyll TeXT theme.
