Bar chart

bar-chart, labeled horizontal bars written as a plain Markdown table.

A bar chart is a container whose body is a Markdown table: label, value, and an optional note. The table is also the accessible output and the fallback in any plain Markdown renderer.

Attributes

Attribute Values Default
title any text none
max number that fills a bar completely 100
unit suffix shown after values %
caption caption text when no paragraph follows the table none

Every directive also accepts id, which becomes the HTML id; see Syntax and metadata.

Each value must be a number from 0 to max. A non-numeric value or a value above max is a validation error that names the row.

Context Snowball

The trailing paragraph is the caption, rendered italic and centered.

:::bar-chart{title="Context Snowball"}
| Turn | Context used | Size |
| --- | --- | --- |
| Turn 1 | 2 | ~4K tokens |
| Turn 10 | 35 | ~70K tokens |
| Turn 25 | 75 | ~150K tokens |
| Turn 50 | 100 | ~200K (full window) |

Every turn re-sends the whole conversation. On a 50-turn session, that's roughly **25 input tokens for every 1 output token** - illustrative, not a measured trace.

Custom max and unit

max is the value that fills the bar. Cells may repeat the unit.
