Markdown is a beautiful demonstration that document structure syntax can/should be simple. What most people do in Word is better done by just adjusting the document rendering/style, not the document structure...

I love the idea of extending markdown to include more visual elements, but if you're not careful you just reinvent HTML.

Here's my personal take on extending table syntax for charts. Easy to write, and if a renderer/parser understands the syntax you get a beautiful chart, and if it doesn't you get a table with slightly weird headings:

  | Month::x | Revenue::y1 | Cost::y2 |
  | -------- | ----------: | -------: |
  | Jan      | $82,000     | $51,000 |
  | Feb      | $91,000     | $56,000 |
  | Mar      | $95,000     | $58,000 |

What's the : in the divider?

That's header alignment marker. If it's on right, the header cell is aligned to right.

Nice project. But at what point does Markdown just become Emacs Org-Mode? At least with Emacs you can write Lisp to make your document do anything you want.

Deepening on who your users are you might also say "at least with markdown they write Lisp and make their documents do whatever they like."

I work on a dashboarding / BI solution that is also built around markdown and clickhouse. www.evidence.dev

We moved to stripe's Markdoc variant for the component syntax last year and have been really happy with it. Models are good at writing it, people are good at reviewing it.

Here's an area chart that would issue a SQL query for weekly revenue totals:

``` {% area_chart data="my_table" x="date" y="sum(revenue)" date_grain="week" /%} ```

Looks cool.

I continue to love Markdown and always push it a bit further than Commonmark, with frontmatter, schemas, code fence metadata too.

I've been enjoying https://djot.net/ as a superset of Markdown that is feels very well designed and extensible too.

You may look into its syntax and tooling for prior art or some extra lift.

I'm trying to get a djot extension in Zed for syntax highlighting if anyone minds adding a to help signal some community interest.

I'm using quarto for this sort of thing.

Very cool.

I’m a product designer, and I could totally see this fitting into my workflow for design briefs, strategy, review, and crit docs. Markdown is too simple, and Figma is too visual. This feels like a great middle ground.
