/**
|
|
* `render_chart` — the agent describes the data it wants to visualize and we
|
|
* render it as a **native Teams chart** (an Adaptive Card chart element), no
|
|
* image generation involved. This is the "upload a CSV → get a chart" payoff:
|
|
* the agent parses the data (the CSV arrives as readable text via the adapter's
|
|
* inbound-file handling), then calls this with a simple `{label, value}` series.
|
|
*
|
|
* Native charts render right inside the card, so there's no headless browser,
|
|
* no Chromium, and no PNG upload, so the bot stays a pure Node service.
