# Datatype Demo

Datatype turns compact text expressions into small inline charts. PathMX authors can keep the source readable while adding quick visual signals directly in prose, lists, and tables.

## Inline Signals

Course confidence is trending up {l:18,24,35,44,51,67,76,82}, but the latest quiz still has a few uneven spots {b:35,80,55,92,68}.

The completion slice for this module is {p:72}.

## Learning Snapshot

| Signal | Datatype | Note |
| --- | --- | --- |
| Weekly participation | {l:32,40,38,56,68,74,81} | Slow start, steady finish |
| Lab completion | {b:92,86,88,94,90} | Consistently high |
| Current mastery | {p:64} | Room for review before assessment |

## Authoring Source

The charts above are authored as ordinary markdown text:

```md
Course confidence is trending up {l:18,24,35,44,51,67,76,82}
Lab completion {b:92,86,88,94,90}
Current mastery {p:64}
```

Because the syntax stays text-first, the source remains legible to people, search tools, and agents.
